Sono-Elastography in evaluation of the median nerve in carpal tunnel syndrome patients

Abstract

n this study 7 wrists were diagnosed with mild Carpal tunnel syndrome(CTS) , 5 wrists demonstrated moderate cases , whereas only 3 wrists revealed severe cases. Cross sectional area (CSA) and elasto ratio of the median nerve was found to increase with the severity of entrapment. Combination of CSA and Elastography images at both the wrist and distal forearm proved to add a value for diagnosis of the patients than each of them individually. To summarize, Ultrasound examination in combination with elastography is a well-tolerated, non-invasive, and cost-effective diagnostic tool in carpal tunnel syndrome patients, thus can be used to follow up patients with reliable results in comparison to the painful nerve conduction velocity studies.
