Abstract:
To compare the diagnostic value of high-resolution uhrasonography (HR-US) with nerve conduction study (NCS) in patients with clinically defined carpal tunnel syndrome (CTS),a prospective study was conducted on 37 consecutive patients investigated for sensory hand symptoms. With the clinical diagnosis of CTS as gold standard,NCS showed higher diagnostic sensitivity (80％)than ultrasound (61％) (P =0.047 ).The positive predictive value of HR-US for CTS was 100％.The results indicated that HR-US could be used as a screening method for majority of clinically suspected CTS patients and only for those with negative HR-US results.
