Note normal marrow signal intensity (M).
Note normal marrow signal in the first metatarsal head (asterisks).
On T1-weighted images, the bone marrow signal intensity is diffusely decreased with additional foci interspersed.
Bone marrow signal change is limited and soft tissue involvement is more common.
b Contusion: subchondral marrow signal changes representing oedema (arrows), without cortical depression.
The MR images (b) show marrow signal changes (dashed arrows) at the articular surface of the talocaneal coalition.
MRI may reveal tendinosis and abnormal bone marrow signal within the ossicle and the adjacent osseous structures (Fig. 18).
Sagittal STIR image (a) shows minimally increased T2 signal in the disc posteriorly and preserved marrow signal.
Increased bone marrow signal, denoting inflammation in the SIJ, vertebral bodies, and posterior spine elements was assessed on STIR sequences.
Bone marrow signal in the anterior superior Iliac spine was relatively normal with only a subtle oedema seen.
In diabetic patients, abscess formation is frequently associated with osteomyelitis and its characteristic bone marrow signal alterations [42].
