1高频超声检查在腕管综合征病情判断中的应用价值显示文摘目的探讨高频超声检查判断腕管综合征病情的价值。方法选择腕管综合征患者28例(共41腕)作为观察组,其中轻度14腕、中度10腕、重度17腕;健康志愿者21例(共21腕)作为对照组。两组均行肌电图运动单位计数技术(MUNE)检查及高频超声检查;比较两组高频超声参数豌豆骨和钩骨钩截面腕横韧带厚度、前后径、左右径、正中神经扁平率及MUNE值;分析高频超声参数与MUNE值的相关性。结果观察组钩骨钩截面腕横韧带厚度、豌豆骨与钩骨钩两个截面前后径、左右径,正中神经扁平率均高于对照组(P均<0.01),观察组MUNE值低于对照组(P<0.05)。观察组轻度者豌豆骨截面正中神经扁平率、钩骨钩截面腕横韧带厚度、钩骨钩截面正中神经扁平率均低于中、重度者,P均<0.05;MUNE值高于中、重度者,P均<0.01。豌豆骨与钩骨钩两个截面的正中神经扁平率与MUNE值均呈负相关(P均<0.05);两个截面的腕横韧带厚度与MUNE值均无相关性(P均>0.05)。结论高频超声检查与MUNE检查结果有较好的相关性,可较好地反映腕管综合征的病情。孙明昊 李斌 王文静 苏兰 牟振弘 张玉香 张哲成 2015山东医药2015,55,32:7
2Grey-scale sonography and sonoelastography for diagnosing carpal tunnel syndrome显示文摘Carpal tunnel syndrome(CTS) is a common peripheral entrapment neuropathy of the median nerve at wrist level, and is thought to be caused by compression of the median nerve in the carpal tunnel. There is no standard quantitative reference for the diagnosis of CTS. Greyscale sonography and sonoelastography(SEL) have been used as diagnostic tools. The most commonly agreed findings in grey-scale sonography for the diagnosis of CTS is enlargement of the median nerve cross-sectional area(CSA). Several authors have assessed additional parameters. 'Delta CSA' is the difference between the proximal median nerve CSA at the pronator quadratus and the maximal CSA within the carpal tunnel. The 'CSA ratio' is the ratio of CSA in the carpal tunnel to the CSA at the mid forearm. These additional parameters showed better diagnostic accuracy than CSA measurement alone. Recently, a number of studies have investigated the elasticity of the median nerve using SEL, and have shown that this also has diagnostic value, as it was significantly stiffer in CTS patients compared to healthy volunteers. In this review, we summarize the usefulness of grey-scale sonography and SEL in diagnosing CTS.Hideaki Miyamoto Yutaka Morizaki Takahiro Kashiyama Sakae Tanaka 2016World Journal of Radiology2016,8,3:5
