Examination: MRI OF
THE RIGHT WRIST
CLINICAL HISTORY:
39 -year-old female with history of scaphoid
fracture and wrist pain
MRI TECHNIQUE:
Coronal GRE T2, PD, axial PD, FIR, coronal T2 and
sagittal PD images of the right wrist were obtained
on a 0.2 Tesla open MRI.
MRI FINDINGS:
The proximal pole of the scaphoid is not well
visualized and appears deformed. There is abnormal
T2 hyperintense signal throughout the scaphoid and
the lunate. Radiocarpal, intercarpal and
carpometacarpal alignments are maintained. There is
no gross disruption of the scapholunate ligament or
triangular fibrocartilage complex. The
lunotriquetral ligament is not visualized. Dorsal
extensor tendons are intact. Flexor tendons in the
carpal tunnel are preserved and there is no mass in
the carpal tunnel. There is effusion in the distal
radioulnar and intercarpal joints |

IMPRESSION:
|
|
|
|
| |
|
 |
Findings are suggestive of fracture scaphoid.
No evidence of avascular necrosis at this
time, but this maybe beyond the resolution
of the scanner, and a CT or higher
resolution MRI would be more helpful. |
|
|
Abnormal signal involving the lunate bone,
likely representing bone bruise/bone edema;
subtle fracture cannot be excluded |
