Myelofibrosis and mastocytosis incite such prominent sclerosis that the marrow is very dark on both T1 and T2; a similar appearance to the marrow in hemosiderosis in patients with hemolysis from sickle cell disease and thalassemia. T1-weighted imaging: Both red and fat marrows contain lipid and water with various proportions. Eur Radiol. Objective: To describe the magnetic resonance (MR) appearances of the bone marrow of children's feet and to determine their frequency and significance. 1995;25(8):588-95. Saifuddin A, Tyler P, Rajakulasingam R. Imaging of Bone Marrow Pitfalls with Emphasis on MRI. The study concluded with the admonition that abnormal bone marrow findings on MRI should not be ignored. Dietrich O, Biffar A, Reiser MF, Baur-Melnyk A. Diffusion-weighted imaging of bone marrow. Within long bones, it occurs first in the proximal metaphysis, then distal metaphysis, and finally diaphysis. With the exception of the diploic venous channels, the calvaria normally does not enhance after the administration of intravenous contrast material ( 1 , 3 ). Federal government websites often end in .gov or .mil. 22, Behrang Amini, Krina Patel, Kaye D.

Shah L & Hanrahan C. MRI of Spinal Bone Marrow: Part I, Techniques and Normal Age-Related Appearances. Amer HZ, Hameed M. Intraosseous benign notochordal cell tumor. They are commonly asymptomatic and multiple. A heterogeneous medical condition or heterogeneous disease is a medical term referring to a medical condition with several etiologies (root causes), such as hepatitis or diabetes.Medical conditions are normally defined pathologically (i.e. 6 However, it is important to recognize that completely fatty replaced marrow will also not show signal loss. However, false negative results can rise from fat-containing metastasis (e.g., from renal cell carcinoma) and false positive results can results from marrow fibrosis as well as susceptibility artifacts accompanying marrow hematomas and sclerotic metastasis[25,27]. Imaging findings on MRI include sacroiliac joint effusion and synovial outpouching, surrounding reactive bone marrow edema and enhancement in both the sacrum and iliac bones, loss of the normal low-signal-intensity margins of cortical bone, and rim-enhancing abscess formation in the adjacent iliopsoas muscle or paraspinal soft tissues (Fig. Radiology. Sometimes, these focal lesions can show increased signal intensity on T2 FSE sequences. Silva JR, Hayashi D, Yonenaga T, Fukuda K, Genant HK, Lin C. MRI of bone marrow abnormalities in hematological malignancies. Very bright marrow signal on STIR is more likely to represent pathologic infiltration. A more pronounced form can show up in some hematologic disorders (e.g., Hemolytic anemias) and malignancies as well as patients treated with granulocyte colony stimulating factors (GCSF) used to relive marrow suppression associated with chemotherapeutic regimens[77,78]. The following risk factors, in addition to femoral neck bone mineral density, are used in FRAX (Fracture Risk Assessment Tool), which calculates a 10-year probability of major osteoporotic fracture (hip, clinical spine, humerus, or wrist fracture) and hip fracture 11: body mass index(lower body mass carries higher risk), daily alcohol consumption of at least 3 units, ever long-term use of oral glucocorticoids (more than 3 months at a dose equivalent to as least 5 mg daily prednisolone), other causes of secondary osteoporosis, including, HIV/AIDS, especially with some antiretroviral therapy (ART)(e.g. However, this is not absolute and a cut off value of 20% signal drop has postulated[24]. However, there is much overlap between ADC values of hypercellular, but normal, red marrow and malignancy. Routine evaluation of spinal marrow will include spin echo T1 and T2W pulse sequences in the sagittal plane. At birth, the whole spinal marrow is metabolically active (hematopoietic/red marrow). At the time the article was created Hom Prasad Pant had no recorded disclosures. 14 , 15 , 16. (n.d.). Bianchi M, Mazzanti A, Galbiati E et al. Mild regional forms can be seen in endurance athletes, obese subjects and heavy smokers[15,76]. Generally speaking, the earlier a doctor diagnoses cancer, the better your chances for survival. Check for errors and try again. This technique may also help differentiate benign from malignant compression fractures based on the same principles in which a malignancy will completely replace fat with cellular tumor before causing pathologic collapse. Incidental detection of hematopoietic hyperplasia on routine knee MR imaging. Spinal marrow heterogeneities may be seen in all spinal regions but it is more common in the lumbar spines[1,6,9]. Laredo JD, Reizine D, Bard M, Merland JJ. Design and patients: A review of MR studies obtained in a retrospective series of 35 children with foot pain and in a prospective series of 19 asymptomatic children was performed. Diffuse metastatic disease: Usually multifocal lesions rather than diffuse, uniform replacement. Accessibility Bone Mineral Density and Bone Metabolism in Duchenne Muscular Dystrophy. Normal variant: In the adult patient, normal conversion from red to yellow marrow may be patchy in a multifocal manner. Yellow marrow can also be seen focally in vertebra around the basivertebral vein, adjacent to degenerative disc disease and Schmrl nodes, and within hemangiomas. Red-yellow marrow conversion: its effect on the location of some solitary bone lesions. The authors prefer to use the STIR in the coronal plane to discourse the neutral axis and its meningeal sleeves, especially in cervical and lumbar regions, abnormalities of the facets and sacroiliac joints and exploration of accidental extra-spinal pathologies not apparent on routine sagittal and axial planes. Bone marrow changes in adolescent girls with anorexia nervosa. I. Cranial Bone and Spine. Available from: Bordalo-Rodrigues M, Galant C, Lonneux M, Clause D, Vande Berg BC. Bollow M, Knauf W, Korfel A, Taupitz M, Schilling A, Wolf KJ, Hamm B. 3. Received 2015 Jun 2; Revised 2015 Sep 29; Accepted 2015 Oct 23. They are incidental finding on radiologic and histologic examinations and have to be distinguished from chordomas to save inadvertent extensive surgeries[82]. 5. The marrow signal was originally interpreted as diffusely abnormal with concern for malignancy, which led to a referral to a cancer center for further evaluation. Hence the mineral-to-osteoid ratio is normal (cf. It can be confused with diffuse marrow infiltrative processes in the vertebral marrow thanks to both red and fat marrow cohabitation. Before 6. ADVERTISEMENT: Supporters see fewer/no ads. An official website of the United States government. Jain R, Singh ZN, Khurana N, Singh T. Gelatinous transformation of bone marrow: a study of 43 cases. Diagnostic clues that suggest benign red marrow: Red marrow reconversion is symmetric and bilateral (more helpful when evaluating coronal images of the pelvis and sacrum than on a routine spine MR). (2023). Depending on those findings and your symptoms, diagnostic testing may involve: The results of the biopsy can confirm a bone marrow cancer diagnosis and provide information about the specific type of cancer. raloxifene), denosumab, strontium ranelate, calcitonin, and parathyroid hormone-based treatments (e.g. On routine CTs (performed at 120 kV), L1 vertebral body trabeculation measuring less than 90-135 HU suggests osteoporosis, with higher values in this range being more sensitive and lower values being more specific 13. - 69.163.204.241. That is why recognition of this physiologic phenomenon is mandatory to rule out underlying myeloproliferative disorder on MR imaging. 2008;246(3):66274. Normal marrow that is rich in protons will show free diffusion and high ADC values (i.e., high signal intensity on both the diffusion image and ADC map)[31,32]. Symptoms will depend on the type of cancer you have. Hajek PC, Baker LL, Goobar JE, Sartoris DJ, Hesselink JR, Haghighi P, Resnick D. Focal fat deposition in axial bone marrow: MR characteristics. On the contrary, a high lipid content of yellow marrow returns high signal intensity comparable to that of subcutaneous fat on T1W images[16]. In normal adults spinal marrow doesnt show perceptible enhancement following administration of gadolinium based T1W agents[17,37,38]. Open-Access: This article is an open-access article which was selected by an in-house editor and fully peer-reviewed by external reviewers. Gelatinous degeneration of the bone marrow mimicking osseous metastasis on 18F-FDG PET/CT. Nishiguchi T, Mochizuki K, Ohsawa M, Inoue T, Kageyama K, Suzuki A, Takami T, Miki Y. Differentiating benign notochordal cell tumors from chordomas: radiographic features on MRI, CT, and tomography. They are common in vertebral bodies than posterior elements. The https:// ensures that you are connecting to the Miller TT. The imaging characteristics are as follows: DWI (diffusion-weighted imaging): restricted diffusion, high in signal. Death rates have fallen an average of 1.9 percent each year from 2010 to 2019. This requires the radiologist to be acquainted with normal MR patterns of the spinal bone marrow, its chronological conversion, and its different common variants. A non-selective 180 inversion pulse applied at specified inversion time followed by refocusing 90 pulse can cancel any signal from fat and the returning signal will be of the non-fatty components, e.g., water[10,21]. Riley RS, Williams D, Ross M, Zhao S, Chesney A, Clark BD, Ben-Ezra JM. Vertebral hemangiomas: radiologic evaluation. interpretation of the bone marrow aspirate and biopsy. Note areas of low signal intensity under the anterior cortex of multiple adjacent vertebral bodies (short white arrows) corresponding to focal nodules of red marrow. Lichy MP, Aschoff P, Plathow C, Stemmer A, Horger W, Mueller-Horvat C, Steidle G, Horger M, Schafer J, Eschmann SM, et al. FOIA Decreased bone density can be appreciated by decreased cortical thickness and loss of bony trabeculae in the early stages in radiography. Its an evolutionary self-preservation. Also, islands of red marrow may be seen anywhere in the skeleton, typically in a subcortical distribution, often with central yellow marrow giving it a bull's eye appearance on axial imaging. MRI is the investigation of choice for bone marrow imaging; it helps detect marrow changes that may be occult on CT/radiograph (Cotten 2019). A clinical diagnosis of osteoporosis may also be established without bone mineral density measurement by the presence of a fragility fracture, particularly at typical sites (spine, hip, pelvis, wrist, humerus, or rib). Diffusion-weighted MR imaging offers no advantage over routine noncontrast MR imaging in the detection of vertebral metastases. This has proved beneficiary in differentiation neoplastic and osteoporotic fractures[25,26]. 2009;250(1):28-38. The signs and symptoms may include: Leukemia usually involves WBCs. In-phase and out-of-phase MR imaging of bone marrow: prediction of neoplasia based on the detection of coexistent fat and water. Radiology Review Manual. Blebea JS, Houseni M, Torigian DA, Fan C, Mavi A, Zhuge Y, Iwanaga T, Mishra S, Udupa J, Zhuang J, et al. Hematopoietic and fatty bone marrow distribution in the normal and ischemic hip: new observations with 1.5-T MR imaging. Additionally, this is more complicated by age- and sex-related variations as fat marrow is higher in men than women[49,58] and water content is higher in females child-bearing age[59]. Your oncologist is there to help you understand your diagnosis and treatment options. A Case of Focal Haematopoietic Hyperplasia of a Vertebral Body and Review of the Modern Literature. Thorax, Pelvis and Extremities. They are not uncommon finding on daily spinal MR evaluations and should not raise clinical awkward. If these tests are normal, no further workup is necessary. Wu JS, Hochman MG. Also they can differentiate bone metastasis from infection[44]. Radiology. Baur A, Stbler A, Bartl R, Lamerz R, Scheidler J, Reiser M. MRI gadolinium enhancement of bone marrow: age-related changes in normals and in diffuse neoplastic infiltration. CrossRef Any suspicious bone marrow lesion on the routine planes could be ascertained on this additional coronal STIR image. The World Health Organization (WHO)operationally defines osteoporosis as a bone mineral density T-score less than -2.5 SD (more than 2.5 standard deviations under the young-adult mean), which is measured by dual-energy x-ray absorptiometry (DEXA), in postmenopausal women and men at least 50 years old. Differentiation of osteoporotic and neoplastic vertebral fractures by chemical shift {in-phase and out-of phase} MR imaging. There is no microstructural and biochemical change as occurs in osteomalacia or rickets. 28.1b; T2WI), no focal areas of increased signal are seen and the marrow remains iso- to hypointense relative to skeletal muscle. The bone marrow signal is heterogeneous with large, multifocal, patchy but ill-defined, areas of slightly lower signal intensity on the T1WIs. Bone marrow cancer happens when cells in the marrow begin to grow abnormally or at an accelerated rate. Vande Berg BC, Lecouvet FE, Galant C, Simoni P, Malghem J. Focal nodular hyperplasia of the hematopoietic marrow simulating vertebral metastasis on FDG positron emission tomography. Imaging has a crucial position in diagnosing and managing bone tumors, which ultimately warrants a multidisciplinary approach. Quantitative ultrasound of the calcaneal bone quality has recently emerged as a cost-efficient screening tool for osteoporosis 10. Initial experience with dynamic MR imaging in evaluation of normal bone marrow versus malignant bone marrow infiltrations in humans. Tumors form when your body starts to produce too many plasma cells. Google Scholar. Conventional sequences used basically to image marrow include T1W, fat-suppressed T2W and short tau inversion recovery (STIR) imaging provides gross morphological data. The normal spinal marrow may show mild homogenous contrast enhancement in neonates and pediatrics due to abundant blood flow, prominent extravascular space and rich diverse cellularity[17,37]. Similarly . Check for errors and try again. How long can you have cancer without knowing it? An analysis of physiological signal behavior]. In lymphoma, lymphocytes, or cells, grow out of control, forming tumors and making it difficult for your immune system to do its job. This requires the radiologist to be acquainted with the used MR techniques to judge the spinal marrow as well as its normal MR variants. Costelloe CM, Madewell JE. Radiology. Patterns 2 and 3 are seen more commonly with advancing age. It is important to understand that although patchy, heterogeneous marrow signal may be seen in the normal older population, this appearance does not exclude the possibility of metastatic disease or especially that of multiple myeloma. Woertler K. Benign bone tumors and tumor-like lesions: value of cross-sectional imaging. In the same vertebral body of an adult, bone marrow is homogenously distributed with more abundance of the cellular red-marrow (50% of the spinal marrow by age of 70 years) near the endplates and anterior portion of the vertebral body while fat marrow is abundant around the basi-vertebral vein[2,60]. 1. In leukemia, the body produces abnormal blood cells that do not die off as they should. Deutsch AL, Mink JH, Rosenfelt FP, Waxman AD. Diffusion magnetic resonance imaging to differentiate degenerative from infectious endplate abnormalities in the lumbar spine. Clinical trials are research programs that test new treatments that have not yet been approved for general use. It could be in response to physiologic stimuli as in obesity, cigarette smokers and heavy training athletes; or pathologic conditions as chronic hemolytic anemias and marrow replacing disorders[2,13,14]. However, it is important to recognize that these variations have to be homogenous between vertebral bodies of the same subject[54]. The red marrow appears as low signal due to its higher water content on T1W images yet it has to be higher than that of intervertebral discs and paraspinal muscles[16]. Simon GH, Raatschen HJ, Wendland MF, von Vopelius-Feldt J, Fu Y, Chen MH, Daldrup-Link HE. These pathologic changes are recognized on MR as fat-poor marrow, which emits water-like signal on all pulse sequences, i.e., low on T1W and high on T2W and STIR sequences[3,93]. Metastatic and infiltrative marrow neoplasia will destroy normal marrow and retain high water content with resultant high-signal on out-phase imaging[23]. During infancy red marrow occupies the entire ossified skeleton except for epiphyses and apophyses. Radiological reasoning: bone marrow changes on MRI. Levine CD, Schweitzer ME, Ehrlich SM. Bone tumors: magnetic resonance imaging versus computed tomography. David Sutton. Part of Springer Nature. Its not clear what causes bone marrow cancer. Cancer stat facts: Hodgkin lymphoma. On the fat-suppressed T2WIs, it is not significantly higher in signal than skeletal muscle. 2016;280(4):350-8. Appointments 216.444.2606. 2. 2019;52(4):20926. Long SS, Yablon CM, Eisenberg RL. Musculoskeletal MRI. These spatial and sex-related changes are common between individuals of the same age group. The other type, non-Hodgkins lymphoma, starts in B or T lymphocytes. Methods. At the time the article was last revised Angela Liao had no recorded disclosures. Nevertheless,dual energy x-ray absorptiometry (DEXA) is the gold standard of diagnosing osteoporosis 10. not a sensitive modality, as more than 30-50% bone loss is required to appreciate decreased bone density on a radiograph, loss of cortical bone and trabecular bone (ghost vertebra), compression fractures and vertebra plana (Genant classification of vertebral fractures), prominent vertical (primary) trabeculae with thinning of horizontal/secondary trabeculae in vertebral bodies, loss of trabeculae in the proximal femur area, which is explained by Singh's index(and can also be seen in the calcaneum), in tubular bones (especially metacarpals), there will be thinning of the cortex, cortical thickness <25% of the whole thickness of the metacarpal signifies osteoporosis (normally 25-33%). Ross JS, Masaryk TJ, Modic MT, Carter JR, Mapstone T, Dengel FH. Zajick DC, Morrison WB, Schweitzer ME, Parellada JA, Carrino JA. Another less commonly used class of MR contrast agents affect the T2- or T2* imaging characteristics. Examine the signal intensity of paraspinous musculature in an area that is least fat infiltrated on parasagittal images, to the side of midline. Under certain conditions, there may be premature conversion of red marrow into the fat type with increased MR signal compared to the age and sex matched subjects. 1998;8(8):1327-34. Also, MRI accurately provides us knowledge about the anatomical relationship of tumors from important bony landmarks and helping the surgeon to understand possible crossing of physeal plates or joints (Davies 2009; Wu 2012). On fat-suppressed T2W and STIR images (Figure (Figure3),3), the red marrow emits an intermediate signal slightly higher than adjacent paravertebral muscles against the black background of suppressed fatty marrow. Tumor detection by diffusion-weighted MRI and ADC-mapping--initial clinical experiences in comparison to PET-CT. Costa FM, Ferreira EC, Vianna EM. Taccone A, Oddone M, Dell'Acqua A, Occhi M, Ciccone M. MRI "Road-Map" of Normal Age-Related Bone Marrow. Detti B. Survival rates for childhood leukemias. From the archives of the AFIP. Vertebral bone marrow chemical composition and cellular buildup. It is thought as a benign osseous hamartoma of developmental origin[72]. Proceedings of UK Radiological Congress 1997. Your oncologist can tell you what cancer you have, as well as what symptoms and treatment you can expect. However, it is not widely used clinically as same information could be achieved by the above used tools. Carroll KW, Feller JF, Tirman PF. Its benign nature is ascertained by corresponding high-signal intensity on T1W images due to its abundant fat content (Figure (Figure77)[67]. 8600 Rockville Pike osteomalacia in which the mineral-to-osteoid ratio is decreased). This makes T1W the moneys worth sequence of MR screening of bone marrow[3,17,18]. ADVERTISEMENT: Supporters see fewer/no ads. 9. Acute leukemia involves immature blood cells, called blasts, and symptoms can progress quickly. Baudrez V, Galant C, Vande Berg BC. 24A . A recent report described malignant, transformation into chordoma of L1 vertebral body supporting the postulation of a relation of the two entities[84]. Daldrup-Link HE, Rummeny EJ, Ihssen B, Kienast J, Link TM. 10. The bone marrow signal is heterogeneous with large, multifocal, patchy but ill-defined, areas of slightly lower signal intensity on the T1WIs. The increased use of magnetic resonance imaging (MRI) has resulted in reports of incidental abnormal bone marrow (BM) signal. 2010;48(3):497-518. 20, Beyond the neonatal period, hypointense marrow signal that is lower than adjacent skeletal muscle and intervertebral disk spaces on T1WIs is almost always pathologic. http://www.birpublications.org/doi/abs/10.1259/conf-pukrc.1997. Sagittal T1W (A), T2W (B) and coronal STIR (C) images of the dorsal spines of a 60-year-old male with mild scoliotic deformity of the mid dorsal region. This myth has been widely debunked. Bone mineral density (BMD) measurement is the method of estimation of calcium hydroxyapatite. The function of bone marrow is to provide different blood cell lineages involved in tissue nutrition, oxygenation and bodys immune reactions[7]. The two case presentations that follow demonstrate unquestionably abnormal bone marrow signal changes, both of which were due to hematological malignancy. Benign vertebral hemangioma: MR-histological correlation. In-phase/opposed-phase imaging. Mohamed Ragab Nouh, Faculty of Medicine, Alexandria University, Alexandria 21563, Egypt, Ahmed Fathi Eid, National Guard hospital, Al Ehsa 31982, Eastern Provience, Saudi Arabia. In the latter section the normal spinal marrow MR patterns and common variants are displayed. This sign has been reported to have 95% sensitivity and 99.5% specificity for benignancy. The authors would thank to Dr. Osamah Al Atyah, anesthesia and ICU Consultant, Hussein Al Ali Hospital, Al Ehsa, Saudi Arabia, for his critical linguistic revision of the final manuscript. Get information on the prognosis, life expectancy, and survival rates. Marrow is the sponge-like material inside your bones. Chemical-shift imaging: Chemical-shift or opposed phase imaging relies on the fact that water and fat have different resonance frequencies so that when they are resonating aligned their signal is summed (in-phase imaging) while when they are opposed (out-phase imaging) their signals are subtracted with subsequent signal drop[23]. Cross-Sectional Imaging in Skeletal Oncology. It has to be considered as a normal variation of the bone marrow for the health status of those subjects and not a pathologic marrow disease. Baur A, Dietrich O, Reiser M. Diffusion-weighted imaging of bone marrow: current status. Chemical shift imaging is an excellent problem-solving technique and can help distinguish red marrow from pathologic infiltration. The MR appearances on T1-weighted, T2-weighted and STIR . Bone tumors and tumorlike conditions: analysis with conventional radiography. Palmer W, Bancroft L, Bonar F et al. According to the National Cancer Institutes Surveillance, Epidemiology, and End Results (SEER) Program data from 2011 to 2017, the five-year relative survival rates for multiple myeloma are: Some types of leukemia can be cured. What Is the Life Expectancy with Stage 4 Bone Cancer? Plain radiographs are quintessential for initial workup and should always be performed to diagnose a bone tumor. Br J Radiol. Magnetic resonance imaging of the normal bone marrow. Hence, their proportions are the main determinants of spinal marrow MR signal characteristics[8-10]. Osteoporosis. Further contrast MRI can show the necrosis and change in the size of soft tissue lesion guiding in response evaluation after neoadjuvant chemotherapy. When found early, both adult and childhood Hodgkins lymphoma can usually be cured. Bisphosphonates and denosumab have been associated with rare, but serious, side effects including bisphosphonate-related atypical femoral fractures and bisphosphonate-related osteonecrosis of the jaw. Marrow: red, yellow and bad. Toumba M & Skordis N. Osteoporosis Syndrome in Thalassaemia Major: An Overview. Bulls eye sign: Normal red marrow often has focal areas of preserved increased signal on T1WIs due to the presence of macroscopic fat. We avoid using tertiary references. Kanis J, Oden A, Johansson H, Borgstrm F, Strm O, McCloskey E. FRAX and Its Applications to Clinical Practice. On the fat-suppressed T2-weighted image ( Fig. Hanrahan CJ, Shah LM. Elsevier Health Sciences; 2019. 21, Pitfalls: False negatives have been reported in multiple myeloma, sclerotic metastatic disease, and renal cell carcinoma. Abnormal bone marrow findings on an MRI should not be ignored. Vogler JB, Murphy WA. Interventional Radiology). Osteoporosis: A Review of Treatment Options. Normal age-related patterns of cellular and fatty bone marrow distribution in the axial skeleton: MR imaging study. Springer, Cham. Castillo M, Arbelaez A, Smith JK, Fisher LL. Whole-body diffusion-weighted MR imaging in cancer: current status and research directions. False positives have been reported in marrow fibrosis and hematomas. Magnetic resonance imaging of the bone marrow in hematological malignancies. Presences within areas rich in red marrow (sub-cortical and around basi-vertebral vein), elongated shape of the lesions, presence of central high-spot on T1W images (Figure (Figure9),9), fuzzy margins are predictors of their benignity[1,3]. 28.3), which has been found to be an indicator of a benign process. Strong PN, Goerke J, Oberg SG, Kelly RB. 2010;2010:537673. The cortex should be intact and not expanded in red marrow reconversion. 3. Signal intensity of normal red marrow is only slightly greater or equal to that of skeletal muscle on fat-suppressed T2WIs. Several patterns of normal red and yellow bone marrow distribution in the spine have been described by Ricci 9. red marrow: hypointense to subcutaneous fat, but hyperintense to muscle and disc (due to scattered fat cells), yellow marrow: hyperintense (follows the signal of subcutaneous fat), red marrow: slightly hyperintense to muscle, usually its signal intensity is slightly lower than that of yellow marrow, but sometimes it can be difficult to distinguish the two, yellow marrow: hyperintense to muscle and iso- to slightly hypointense to subcutaneous fat, yellow marrow:is saturated out (hypointense), normal bone marrow in adults does not enhance visibly, whereas there may be a significant contrast enhancement in normal marrow of a neonate or a small child, enhancement in adults occurs only in pathological marrow, which can be accentuated on post-contrast images with fat saturation.
