Tóm tắt

 PURPOSE: This study aimed to assess the accuracy of median nerve cross-sectional area (CSA) measurements using a handheld ultrasound (HHUS) and a cart-based high-resolution ultrasound. METHODS: Fifteen healthy subjects were prospectively enrolled. Each subject underwent standardized ultrasound evaluations of their median nerves with HHUS and a high-resolution ultrasound by three different providers with different levels of training in musculoskeletal ultrasound. CSA calculations were performed using a standardized method. The primary outcome was the mean difference in CSA (ΔCSA) between the gold standard high-resolution ultrasound and the lower resolution handheld ultrasound, with a noninferiority margin set at ΔCSA <
  2 mm RESULTS: The average CSA of the median nerve across all patients and reviewers using the high-resolution US was >
  0.9 mm CONCLUSIONS: The findings suggest caution for the use of handheld ultrasound in measurements of median nerve CSA because the difference between HHUS and gold standard high-resolution ultrasound was not within the noninferiority margin of 2 mm TYPE OF STUDY/LEVEL OF EVIDENCE: Diagnostic II.
