MR imaging of the wrist in carpal tunnel syndrome.
OBJECTIVE
To determine whether specific parameters measured on MR images correlated to electrophysiological changes in carpal tunnel syndrome (CTS).


METHODS
Prospective clinical examinations were made of 20 patients with suspected CTS. We performed bilateral electrophysiological examinations of the median nerve and bilateral MR imaging of the wrists.


RESULTS
The electrophysiological examination suggested median nerve entrapment in 18 wrists. These wrists were compared to the remaining 22 electrophysiologically normal wrists. In addition, we compared both wrists in 12 patients with unilateral symptoms of CTS without reference to the electrophysiological findings. We found no difference in specific MR parameters between the 2 groups.


CONCLUSIONS
Neither symptoms nor electrophysiological findings in CTS were related to specific MR parameters.
