Diagnosis of carpal tunnel syndrome. Ultrasound versus electromyography

Radiol Clin North Am. 1999 Jul;37(4):859-72, x. doi: 10.1016/s0033-8389(05)70132-9.


This article presents a new technique for diagnosing carpal tunnel syndrome using ultrasound. The ultrasound characteristics of the normal and abnormal median nerve are discussed in relation to carpal tunnel syndrome. The development of ultrasound as a new diagnostic modality for carpal tunnel syndrome is presented in a three-part study correlating the ultrasound measurements of the median nerve and electromyogram of the median nerve. A new algorithm for evaluating patients with carpal tunnel syndrome is presented.
