Normal haematopoietic marrow in the proximal humerus (arrows in a and b). In children, the normal bone marrow is highly cellular (low signal on T1WI and high signal T2 FS WI). With increasing age, a gradual conversion from this highly cellular marrow to fatty marrow occurs (with an increase in the bone marrow signal on T1WI and a decline on T2 FS WI). In long bones, this conversion first involves the epiphyses, then the diaphyses and finally the metaphyses [24]
