【摘要】：目的对腕管综合征(CTS)的超声检查诊断价值进行分析。方法选取临床确诊腕管综合征患者146例(共180只手腕)为病例组,健康志愿者64例(共128只手腕)为对照组,采用超声测量两组腕管钩骨钩截面和豌豆骨截面正中神经的左右径、前后径和腕横韧带厚度,计算正中神经扁平率;采用剪切波弹性成像(SWE)检测两组的正中神经弹性模量。结果 CTS组与对照组比较,钩骨钩截面正中神经扁平率、豌豆骨截面正中神经扁平率、钩骨钩截面腕横韧带厚度具有明显的差异性,诊断指标灵敏度分别为:86.5%、93.5%、95.0%,特异度分别为:73.0%、65.0%、92.0%;正中神经WEmean、FEmean、FRatio CTS组的弹性成像值均高于对照组(P0.05),CTS组正中神经硬度明显高于对照组。结论钩骨钩截面正中神经扁平率及腕横韧带厚度诊断价值较高,剪切波弹性成像技术可以定性和定量评估组织的硬度,二者结合,具有更高的诊断价值。
[Abstract]:Objective to analyze the value of ultrasonography in diagnosis of carpal tunnel syndrome (CTS). Methods 146 patients (180 wrists) with carpal tunnel syndrome were selected as case group and 64 healthy volunteers (128 wrists) as control group. The left and right diameters of median nerve, anteroposterior diameter and thickness of transverse carpal ligament were measured by ultrasound, and the elastic modulus of median nerve was measured by shear wave elastic imaging (SWE). Results compared with the control group, the median nerve flattening rate of the hook section, the median nerve flat rate of the pea bone section and the thickness of the transverse carpal ligament of the hook section in the CTS group were significantly different from those in the control group. The sensitivity of the diagnostic index was 93.5% and 95.5%, the specificity was 73.0% and 65.0%, respectively. The elastic imaging value of the median nerve CTS group was significantly higher than that of the control group (P 0.05%, P 0.05), and the median nerve hardness of the median nerve group was significantly higher than that of the control group (P < 0.05), and the mean value of the median nerve in the median nerve group was significantly higher than that in the control group (P < 0.05). Conclusion the median nerve flattening rate and the thickness of transverse carpal ligament of the hook hook section are of high diagnostic value. Shear wave elastic imaging can be used to evaluate the tissue hardness qualitatively and quantitatively, and the combination of the two techniques has higher diagnostic value.
