Ultrasound Elastography of Carpal Tunnel Syndrome
Sponsor: Da Nang Family General Hospital
Summary
Carpal Tunnel Syndrome (CTS) is the most common peripheral nerve compression disorder in adults. Although electromyography (EMG) is the current gold standard for diagnosis, it is invasive, time-consuming, and may yield false-negative results. Ultrasound elastography, including shear wave elastography and strain elastography, enables non-invasive assessment of median nerve stiffness, reflecting fibrosis and edema. However, data on the combined use of elastography and microvascular imaging in CTS are still limited in Vietnam. This study aims to evaluate the value of advanced ultrasound techniques in diagnosing CTS and grading disease severity, as well as their correlation with clinical symptoms and EMG findings

Interventions
Ultrasound Elastography
* Shear Wave Elastography (SWE): * Performed in the longitudinal plane at the carpal tunnel inlet. * A Region of Interest (ROI) of 1mm will be placed on the median nerve (excluding epineurium). * Stiffness will be measured in kilopascals (kPa). * Three measurements will be taken and averaged. * Strain Elastography (SE): * Assessed using a color map overlay (Blue/Green/Red). * Grading scale (1-4): Grade 1 (Soft/Red) to Grade 4 (Hardest/Blue).
