Fig. (1) Bone marrow reconversion in the lumber spine of a 66-year-old male. MRI demonstrates a diffuse lesion with low signal intensity in the whole spine on the T1 weighted image (left) and high signal intensity on the T2 weighted image (middle). High signal intensity on the T2 weighted image is suppressed on fat suppression image (right). The signal intensity is almost the same as that of the spinal cord.
