Cancer that starts in the bone marrow is called bone marrow cancer or blood cancer. Fluid-sensitive sequences are less helpful than opposed-phase and T1-weighted sequences because both red bone marrow and neoplastic marrow involvement can have increased signal. Bone marrow edema usually resolves itself with rest and physical therapy. Normal marrow contains both hematopoietic/red and fatty/yellow marrow with a predictable pattern of conversion and skeletal distribution on MRI. How do you treat bone marrow edema? On T1-weighted imaging, a normal fatty marrow exhibits high signal intensity. 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. Pediatr Radiol. 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.

The role of MR imaging has been evaluated in each one of these disorders. Thus, the term bone marrow "edema" is not appropriate. 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].
