This study aimed to assess the diagnostic accuracy of Ultrasonography, considering nerve conduction study (NCS) as the gold standard diagnostic modality for carpal tunnel syndrome (CTS).
A cross-sectional study was conducted at the Neurology Department of Allied Hospital, Faisalabad from August, 2020 to January, 2021. NCS and Ultrasonography of wrist were performed for diagnosis of CTS. The sensitivity, specificity, predictive value (NPV), positive predictive value (PPV), and diagnostic accuracy (DA) were calculated for the screening test (Ultrasonography of the wrist), taking NCS as the gold standard.
The mean age of the study population was 41.53 ± 8.80 years, with female pre-dominance (71.66%). The right hand was involved in 24(40%) patients, left hand was involved in 4(6.66%) patients, and both hands were involved in 32(53.33%) patients. Among 60 patients, ultrasonography diagnosed 56 (TP+FN) as having CTS, confirmed via nerve conduction study. Sensitivity, specificity, NPV, PPV, and DA of Ultrasonography of the wrist for CTS were 92.8%, 75%, 42.8%, 98.1%, and 91.6%, respectively.
Based on the sensitivity and specificity, Ultrasonography may assist in diagnosing CTS.
本研究旨在以神经传导研究（NCS）作为腕管综合征（CTS）的金标准诊断方法，评估超声检查的诊断准确性。
于2020年8月至2021年1月在费萨拉巴德联合医院神经科进行了一项横断面研究。对腕部进行NCS和超声检查以诊断CTS。以NCS作为金标准，计算筛查试验（腕部超声检查）的敏感性、特异性、阴性预测值（NPV）、阳性预测值（PPV）和诊断准确性（DA）。
研究人群的平均年龄为41.53±8.80岁，女性占主导（71.66%）。右手受累的患者有24例（40%），左手受累的患者有4例（6.66%），双手受累的患者有32例（53.33%）。在60例患者中，超声检查诊断出56例（真阳性+假阴性）患有CTS，经神经传导研究证实。腕部超声检查对CTS的敏感性、特异性、NPV、PPV和DA分别为92.8%、75%、42.8%、98.1%和91.6%。
基于敏感性和特异性，超声检查可能有助于CTS的诊断。
