【摘要】目的探讨高频超声在诊断和定位受损臂丛神经中相对于肌电图和核磁共振的优势。方法选取150例经过电生理检测诊断为臂丛神经损伤的患者，进行核磁共振检测的同时进行高频超声检测，记录受损人数及损伤类型，与手术治疗后确诊的受损人数和损伤类型结果相比较，计算肌电图检测、高频超声检测与核磁共振检测的敏感度和特异性。结果高频超声诊断臂丛神经的灵敏度为98.62%，特异性为100%，优于核磁共振检测（灵敏度92.41%，特异性100%）；在损伤臂丛神经诊断，特别是早期诊断上，高频超声优于肌电图检测。结论相对于肌电图和核磁共振，高频超声能较灵敏地诊断及定位损伤的臂丛神经，可应用于临床，提高臂丛神经损伤的确诊率，进行早期治疗，提高患者生活质量。

【Abstract】 ObjectiveTo explore the advantages of highfrequency ultrasound in the diagnosis and localization of injured brachial plexus compared to electromyogram and MRI . MethodsOne hundred and fifty patients were diagnosed as brachial plexus injury by electrophysiological examination, and underwent examinations by MRI and highfrequency ultrasound. The number of patients suffering from injury and the type of injury were recorded, and were compared with the definitely diagnosed number and the type after operation respectively. The sensitivity and specificity of electromyogram, highfrequency ultrasound and MRI were calculated. ResultsThe sensitivity and specificity of highfrequency ultrasound for the diagnosis of brachial plexus were 98.62% and 100% respectively, and were higher than those of MRI (92.41% and 100% respectively). For the diagnosis of brachial plexus injury, especially in earlystage, highfrequency ultrasound was superior to electromyogram. ConclusionCompare to electromyogram and MRI, highfrequency ultrasound can be more sensitive in the diagnosis and location of injured brachial plexus, and can be applied clinically to improve the definite diagnosis rate of injuried brachial plexus so that the early treatment can be conducted and the quality of life of patients can be improve .
