What is wrong in the bone marrow?
-
- Bone marrow reconversion: Signal intensity is that of normal red marrow being low T1 signal but still higher than skeletal muscle. Marrow reconversion occurs in the reverse order of normal red to yellow marrow conversion.
What could be the cause in general?
-
- Physiological (e.g. cigarette smoking, obesity, high altitude), iatrogenic (e.g. post erythropoietin treatment), pathological (e.g. diabetes mellitus, severe chronic anaemia).
