Bone marrow reconversion generates a red bone marrow pattern that is in reverse to the normal red-to-yellow distribution.
Bone marrow reconversion occurs when there is increased hematopoietic demand, which may be 1,2:
post granulocyte-colony stimulating factor treatment
post erythropoietin treatment
Signal intensity will be that of normal red marrow being low T1 signal but still higher than skeletal muscle 1,3. In the appendicular skeleton, it tends to be symmetrical and homogeneous, whereas in the axial skeletal it can be heterogeneous/multifocal 1. Marrow reconversion occurs in the reverse order of normal red to yellow marrow conversion 4.
