MR-IMAGING OF THE WRIST IN CARPAL-TUNNEL SYNDROME

Purpose: To determine whether specific parameters measured on MR image s correlated to electrophysiological changes in carpal tunnel syndrome (CTS). Material and Methods: Prospective clinical examinations were m ade of 20 patients with suspected CTS. We performed bilateral electrop hysiological examinations of the median nerve and bilateral MR imaging of the wrists. Results: The electrophysiological examination suggeste d 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 w ithout reference to the electrophysiological findings. We found no dif ference in specific MR parameters between the 2 groups. Conclusion: Ne ither symptoms nor electrophysiological findings in CTS were related t o specific MR parameters.
