Magnetic resonance (MR) of bone marrow was studied in two cases of acute leukemia which showed bone marrow necrosis. Case 1:A 24-year-old female was admitted because of sternum pain and bleeding tendency. She was diagnosed AML based on the peripheral blood picture. ⋯ Most areas of low signal intensity of T1 weighted imaging changed to those of high signal intensity. These observations suggest that necrotized bone marrow seemed to change to fatty marrow along with achieving remission. MR imaging study of bone marrow is useful for evaluating hematopoiesis in hematologic disorders.
