The carpal tunnel: ultrasound display of normal imaging anatomy and pathology.
Ultrasound successfully displays the normal anatomy and pathology of the median nerve in the carpal tunnel. This article reviews the sonographic characteristics of carpal tunnel anatomy, including the superficially situated median nerve, the contained tendons and vessels, and the boundary-forming fibro-osseous landmarks. It emphasizes ultrasound evaluation of the median nerve and the criteria for diagnosis of compressive neuropathy in carpal tunnel syndrome. The techniques for performing sonography for carpal tunnel syndrome are detailed. Ultrasonic imaging is more comfortable for patients, less time-consuming, and less expensive than MR imaging, and achieves equal accuracy in skilled hands.
