Indications
Standard wrist MRI has a wide range of applications, finding use in the assessment of:
-
Tendons around the wrist
-
Wrist and carpal joint cartilage
-
Abutment syndromes (may not be optimal for suspected TFCC involvement)
Positioning
-
Superman position or hand by side if not tolerated. Hand by side only works in a slim patient, as the coil must be as near to the magnetic isocentre as possible.
-
Allow patient plenty of time to find comfortable position
-
Encourage flexed elbow and relaxed shoulder extension rather than extreme positions
-
Movement artefact is a problem due to patient discomfort in the superman position
MRI Scan
- FOV to cover from 2cm proximal to wrist joint line to bases of metacarpals
- High resolution hand and wrist coil

If struggling with homogeneity of fat saturation especially when scanning with hand by side, consider alternative sequences
