These findings are most often seen in the spine, because the long bones of adults are composed primarily of fatty marrow. This MRI cervical spine show diffuse low marrow signal, iso intense to skeletal muscle. 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. Br J Radiol. 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. (n.d.). 1D).

At birth, the skeleton is composed of hematopoietic red marrow that matures to yellow or fatty marrow. These include Overview Symptoms & Diagnosis T1-weighted images show heterogeneously hyperintense signal intensity, but the T2-weighted signal can be variable. The cause of this may be a fracture, cancer, tumor, or it may just be nothing to worry about at all. 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. 2011;197(6):1298-308. 7 21.
