causes of heterogeneous bone marrow signal on mri

Focal fatty marrow islands (Focal fatty metaplasia): A developmental variation of the bone marrow conversion process is the localized aggregates of areas of fat marrow. The other type, non-Hodgkins lymphoma, starts in B or T lymphocytes. When fat and water coexist in the same voxel, their spins will be out of phase periodically due to the lower precessional frequency of fat relative to water. It is recommended to do a CBC (complete blood count), CMP (comprehensive metabolic panel), SPEP (serum protein electrophoresis), UPEP (urine protein electrophoresis), and serum-free light chain assay to exclude the possibility of a hematological disease, especially plasma cell disorders. Normal Spinal Bone Marrow in Adults: Dynamic Gadolinium-enhanced MR Imaging1. From the archives of the AFIP. However, recognizing its high signal on T1W images and vanishing on fat-suppressed images will disclose its nature. Diffusion magnetic resonance imaging to differentiate degenerative from infectious endplate abnormalities in the lumbar spine. Andreu-Arasa V, Chapman M, Kuno H, Fujita A, Sakai O. Craniofacial Manifestations of Systemic Disorders: CT and MR Imaging Findings and Imaging Approach. These changes could be in a focal or diffuse pattern, produced by either yellow or red marrow variant distributions[6,54,61,62]. CrossRef Lesions that are sizable enough to be picked on CT and radiographs are sclerotic in nature. There is a different list of secondary causes for juvenile osteoporosiswith some overlap with adult causes. Chong A, Song HC, Oh JR, Ha JM, Min JJ, Bom HS, Choi YD, Lee JS. Author contributions: Nouh MR had the idea of the manuscript, reviewed the literature, drafted the manuscript and supplied some of the figures; Eid AF supplied some of the figures, critically reviewed the manuscript; Both authors approved the manuscript in its current final form. Clinical trials are research programs that test new treatments that have not yet been approved for general use. The two case presentations that follow demonstrate unquestionably abnormal bone marrow signal changes, both of which were due to hematological malignancy. Some types of bone marrow cancer are much more aggressive than others. Mallinson PI, Coupal TM, McLaughlin PD, Nicolaou S, Munk PL, Ouellette HA. According to SEER data from 2011 to 2017, the five-year relative survival rate for leukemia is 65 percent. Tins B, Cassar-Pullicino V. Marrow changes in anorexia nervosa masking the presence of stress fractures on MR imaging. Ross JS, Masaryk TJ, Modic MT, Carter JR, Mapstone T, Dengel FH. 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. The spine is the largest store of bone marrow in the body[1,2]. The metabolically inactive fat marrow dynamically repopulates into the metabolically active red type, capable of responding to tissues needs of oxygen in a process named marrow reconversion[5,6,13,14]. 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%). 2019;291(2):360-7. 7. Eur Radiol. Can diffusion-weighted imaging be used to differentiate benign from pathologic fractures? Another less commonly used class of MR contrast agents affect the T2- or T2* imaging characteristics. Rahmouni A, Montazel JL, Divine M, Lepage E, Belhadj K, Gaulard P, Bouanane M, Golli M, Kobeiter H. Bone marrow with diffuse tumor infiltration in patients with lymphoproliferative diseases: dynamic gadolinium-enhanced MR imaging. See additional information. Additionally, red marrow is found in subchondral crescents, typical locations include the proximal humerus and femur 2. Strong PN, Goerke J, Oberg SG, Kelly RB. Ricci C, Cova M, Kang YS, Yang A, Rahmouni A, Scott WW, Zerhouni EA. Actually, the relative ratio of fat and water is the main determinant for the MR signal of spinal bone marrow as well as the used MR pulse sequence[1,4,5,9,13,50,51]. 28.3), which has been found to be an indicator of a benign process. (2011) ISBN: 9781609139438 -. Initial experience with dynamic MR imaging in evaluation of normal bone marrow versus malignant bone marrow infiltrations in humans.

Age- and sex-specific differences in the 1H-spectrum of vertebral bone marrow. MRI is the investigation of choice for bone marrow imaging; it helps detect marrow changes that may be occult on CT/radiograph (Cotten 2019). The abnormal signal is due to replacement of the small amounts of fat cells normally found in red marrow, such that T1 signal will decrease to or below the signal from disc or muscle. Murphey MD, Andrews CL, Flemming DJ, Temple HT, Smith WS, Smirniotopoulos JG. Long SS, Yablon CM, Eisenberg RL. In the normal adult, and usually after the age of 10 (90% of children older than 5 years), marrow should be higher in signal than muscle and the intervertebral disks due to the presence of fat interspersed with hematopoietic tissue on T1WIs. PubMed Mitchell DG, Rao VM, Dalinka M, Spritzer CE, Axel L, Gefter W, Kricun M, Steinberg ME, Kressel HY. New research suggests a strong link between a specific protein and pancreatic cancer, which could lead to improved treatment. Learn how they work, their success rates, and possible risks. Objective: To describe the magnetic resonance (MR) appearances of the bone marrow of children's feet and to determine their frequency and significance. Since treatment is rapidly improving, its possible that survival rates are better than these figures indicate. Following intravenous gadolinium-based contrast media administration, the red marrow; predominantly in children and young adolescents; shows appreciable visual enhancement and increased quantitive parameters on MR dynamic contrast studies inferring its abundant vascularity, well perfusion and increased metabolic activity. Schwartz AV, Sigurdsson S, Hue TF, Lang TF, Harris TB, Rosen CJ, Vittinghoff E, Siggeirsdottir K, Sigurdsson G, Oskarsdottir D, et al. 3. Chronic leukemia involves more mature blood cells. There are also many subtypes. Whole-body diffusion-weighted MR imaging in cancer: current status and research directions. Radiology. The site is secure. This supposed to be mediated via hormonal effects on the preferential differentiation of bone marrow progenitor cells[90]. Careers, Unable to load your collection due to an error. Patterns 2 and 3 are seen more commonly with advancing age. Yellow marrow can also be seen focally in vertebra around the basivertebral vein, adjacent to degenerative disc disease and Schmrl nodes, and within hemangiomas. Ecklund K, Vajapeyam S, Feldman HA, Buzney CD, Mulkern RV, Kleinman PK. II. 1979;25:467-72. They are commonly asymptomatic and multiple.

In the pelvis, fatty marrow replacement begins around the age of 20 years in the superomedial aspect of the acetabulum. moc.oohay@37bagarm. They are common in vertebral bodies than posterior elements. J Osteoporos. Useful internal standards for distinguishing infiltrative marrow pathology from hematopoietic marrow at MRI. Multiple x-ray based, gamma-ray based and ultrasonic methods are available: single photon and x-ray absorptiometry (SPA), quantitative computed tomography can be used. This may necessitate marrow biopsy for histopathologic confirmation. These lesions were found to emit homogenous low- to iso-signal intensity on T1W images and high-signal on T2W images with no enhancement on MR contrast studies[82,83]. Normal bone marrow: dynamic aspects in magnetic resonance imaging. 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. JBJS Rev. Accessibility However, these areas of heterogeneity remain higher in signal than both skeletal muscle and intervertebral disks. Last medically reviewed on January 27, 2022. In the latter section the normal spinal marrow MR patterns and common variants are displayed. Abnormal bone marrow findings on an MRI should not be ignored. However, topographic features of the lesion, i.e., intravertebral, preserved trabecular pattern and non-enhancement following MR contrast administration, are equally important to rule the possibility of chordoma; the extremely malignant spectrum of notchordal cell lineage[82,83]. Modic and colleagues described band-like sub-end plate marrow changes that exhibit water-like (low T1W and high T2W) MR signal for type-I, fat-like (high T1W and T2W signals) for type-II, and calcium-like (low T1W and T2W signals) for type-III Modic changes[64]. Hart JL, Edgar MA, Gardner JM. Their corresponding radiographs and CT examinations will show preserved trabecular and cortical bone. 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. However, the signal is relatively higher than paravertebral muscles on STIR and fat-saturated T2 imaging[1,6,13,14,87,88]. At the time the article was last revised Angela Liao had no recorded disclosures. ochronosis - severe osteoporosis with intervertebral disc calcifications, Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. It is composed of cortical bone layers embedded within the surrounding vertebral marrow cavity and it is usually endosteal surface based. As mentioned earlier, the bone marrow is a mix of red and yellow marrow supported by a trabecular marrow network. 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. These patches still of high-signal intensity on T2W image. A Case of Focal Haematopoietic Hyperplasia of a Vertebral Body and Review of the Modern Literature. 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. Multiple myeloma is not usually curable, but it can be managed. Computed tomography and magnetic resonance imaging of bone tumors. Communicating openly with them will allow you to make the best decision for your treatment. Normal bone marrow: red marrow distribution, appearance on MR, age-related conversion and reconversion 9 , 10 , 11 , 12 , 13 : In the fetus and very early neonatal period, all marrow is hypercellular red marrow. Check for errors and try again. A complete differential diagnosis should include other considerations when abnormal marrow is seen. Recognition of associated disc dehydration and presence of intra-discal gas precludes underling pathologies, e.g., discitis. Heterotopic ossification (HO) occurs when bone tissue develops in your soft tissues. Google Scholar, Rajiv Gandhi Cancer Institute and Research Centre, New Delhi, India, You can also search for this author in Normal fat signal must be suppressed by either inversion recovery (STIR), chemical fat saturation, or m-Dixon techniques in order for the sequence to become sensitive to pathology. Quantitative ultrasound of the calcaneal bone quality has recently emerged as a cost-efficient screening tool for osteoporosis 10. 2009;44(5):734-43. This can be seen in subjects with hypercortisolism (whether endogenous or exogenous) and in some feeding disorders as anorexia nervosa[89]. Visual loss of normal fat stores of the subcutis and inter-tissues fascial spaces will raise this suspicion[93,94]. Tumor detection by diffusion-weighted MRI and ADC-mapping--initial clinical experiences in comparison to PET-CT. Costa FM, Ferreira EC, Vianna EM. Clinical examples include severe hemolytic anemias, heart disease with chronic heart failure, heavy smoking, obesity, endurance athletics, and chemotherapy involving granulocyte colonystimulating factors. The T1WIs are most important for the evaluation of bone marrow. 2020;8(3):e0077. Padhani AR, Koh DM, Collins DJ. By far, magnetic resonance imaging (MRI) is the best imaging modality to depict bone marrow thanks to its inherent soft-tissue contrast and non-ionizing nature[3-5]. Hence, their proportions are the main determinants of spinal marrow MR signal characteristics[8-10]. Most of the above conditions affect the marrow diffusely. Glossary of Terms for Musculoskeletal Radiology. DWI: Typically, there is no restriction of diffusion in the bone marrow outside the neonatal period. On chemical-shift imaging, the red marrow shows no remarkable signal drop on the out-phase image thanks to its near equal contents of both water and fat protons[57]. Br J Radiol. Shah L & Hanrahan C. MRI of Spinal Bone Marrow: Part I, Techniques and Normal Age-Related Appearances. That is why recognition of this physiologic phenomenon is mandatory to rule out underlying myeloproliferative disorder on MR imaging. After that, gradual increased amount of fat cells, especially at the sub-endplates region and anterior part of the vertebral body (Figure (Figure2),2), in the marrow results into the adulthood heterogenous vertebral marrow pattern (Figure (Figure33)[52]. Clinical presentation of bone tumors is challenging. Core tip: Magnetic resonance (MR) remains the ideal noninvasive imaging modality to evaluate vertebral bone marrow. Poulton TB, Murphy WD, Duerk JL, Chapek CC, Feiglin DH. This will include the sub-endplates and subcortical zones and around the basivertebral vein (Figure (Figure44)[5,32,60]. 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. 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]. Check for errors and try again. 4, This heterogeneous marrow signal most likely represents patchy conversion of red to yellow marrow that is a well-described normal variant seen predominantly in older adults. Continue reading to learn about the different types of bone marrow cancer, how theyre diagnosed, and what you can expect. As a rule of thumb, marrow hyperplasia exhibits a signal similar to that of red marrow. A diagnosis of cancer does not always come with a prognosis of pain. This sign has been reported to have 95% sensitivity and 99.5% specificity for benignancy. Rosen CJ, Ackert-Bicknell C, Rodriguez JP, Pino AM. However, at high b values, red marrow may be bright relative to fatty replaced marrow. 1. Silva JR, Hayashi D, Yonenaga T, Fukuda K, Genant HK, Lin C. MRI of bone marrow abnormalities in hematological malignancies. Normal Age-Related Patterns of Cellular and Fatty Bone Marrow Distribution in the Axial Skeleton: MR Imaging Study. Osteoporos Int. We avoid using tertiary references. Learn more about cancer, as well as its connection with fungal infections. Alyas F, Saifuddin A, Connell D. MR imaging evaluation of the bone marrow and marrow infiltrative disorders of the lumbar spine. Standard bone marrow signal depending on yellow (fatty) or red (erythropoietic) marrow composition varies with patient age or any hematopoietic disorder. STIR: Short tau inversion recovery. However, dynamic contrast-enhanced studies have not been widely used in clinical practices. Cancer that affects the bone marrow causes different symptoms depending on the cancer type. They are used to differentiate infiltrative marrow lesions from reactive marrow hyperplasia[43]. Find, When various types of cancer spread to the bones, you may be worried about life expectancy. Bone marrow aspirate and biopsy: a pathologists perspective. 1998;8(8):1327-34. Conversely, yellow marrow has all the same constituents as red, except that fat cells make up the vast majority (80% vs 40% in red marrow), with resulting poor vascularity. Therefore, it is the combination of abnormally low signal on T1WI and lack of signal drop between the in-phase and opposed-phase GRE images that is suspicious for malignant infiltration. II. However, these areas of heterogeneity remain higher in signal than both skeletal muscle and intervertebral disks. Bone marrow imaging. A bone marrow transplant may be a good treatment option for some people with leukemia. This is contradictory to high T2W signal and contrast enhancement seen in neoplastic cases[74,75,79]. The https:// ensures that you are connecting to the All rights reserved. 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]. Baudrez V, Galant C, Vande Berg BC. Awareness of the age-related bone marrow changes as well as changes accompanying different variations of the subjects health state is essential for radiologists. The British Institute of Radiology, 1997; 150. Treatment can improve overall quality of life. Survival rates for childhood leukemias. These are WBCs that make antibodies to protect your body from foreign invaders. Axial and coronal images can be helpful.
