My mri report says "Heterogeneous bone marrow appearance, favored to represent foci of red marrow rather than a diffuse - Answered by a verified Doctor . Abnormal marrow is isointense or hypointense to skeletal muscle on T1-weighted imaging because the replacement of fatty marrow elements by the pathologic process causes loss of the normal fat signal (Fig. Overall, 10% of patients with abnormal marrow on MRI were diagnosed with a malignancy. Chronic leukemia involves more mature blood cells. Calcification is detected in 85% of cases [14, 15]. Heterogeneous abnormal marrow signal is what oncologists look for on a magnetic resonance image of a patient's bone as a possible indication of a malignancy, says the American Society of Clinical Oncology. Most nonneoplastic conditions such as trauma, edema, marrow hyperplasia, ischemia, and infection do not replace bone marrow fat and thus preserve some degree of signal cancellation or dropout on out-of-phase images [21].
