Abstract

Fatty marrow is easy to recognize on Τ1-weighted MR images. Red marrow, however, has to be distinguished from abnormal marrow, and this is one of the main challenges for bone marrow MR imaging. It is imperative to know where to expect red marrow in each age group or where red marrow may reappear under certain conditions. A low-signal-intensity femoral diaphysis on T1-weighted images is likely normal at age 5, but it is definitely abnormal at age 17. Likewise, in a 60-year-old individual, a low-signal-intensity spine on T1-weighted images is an abnormal finding, whereas in a 25-year-old subject, it could be related to the presence of normal red marrow.
