Figure 2 This figure highlights NMUS findings in CTS, showing an enlarged median nerve at the carpal tunnel inlet due to edema and inflammation. The CSA of the nerve is notably increased, a key diagnostic indicator for CTS. In addition, the ultrasound image demonstrates restricted nerve gliding, which is a typical feature of CTS, further confirming the diagnosis. This non-invasive imaging technique provides valuable insights into nerve morphology and assists in differentiating CTS from other conditions with similar symptoms. CSA – cross-sectional area; CTS – carpal tunnel syndrome; NMUS – neuromuscular ultrasound; MN – median nerve.
