摘要目的评估点剪切波弹性成像(p SWE)在传统超声诊断急性胆囊炎中的附加价值。方法对216例临床疑似急性胆囊炎的病人分别行B超、彩色多普勒超声以及p SWE检查。对胆囊行形态学和附壁血管评价并对肝右叶行平均剪切波速度(SWV)评价。2位研究者分别独立回顾了常规超声及常规超声联合p SWE的研究结果。结果与85例对照组相比,91例急性胆囊炎组肝右叶距胆囊2 cm范围内的平均SWV值(m/s)显著升高(1.56∶1.03,1.39∶1.04,P<0.000 1),临界值为1.29或1.16。在急性胆囊炎诊断中,2位研究者观测到附加的对p SWE影像的回顾性分析结果显示,受试者操作特
Abstract Objective To evaluate the value of point-shear wave elastography (p SWE) in the diagnosis of acute cholecystitis by conventional ultrasonography. Methods Totally 216 patients with suspected acute cholecystitis underwent ultrasound, color Doppler ultrasound and p SWE. The morphology of gallbladder and the evaluation of the vessel wall were evaluated and the mean shear wave velocity (SWV) was evaluated on the right lobe of the liver. Two investigators independently reviewed the results of conventional ultrasound and conventional ultrasound in combination with p SWE. Results Compared with 85 control subjects, the mean SWV (m / s) in the right hepatic lobe of 91 patients with acute cholecystitis was significantly higher than that of the gallbladder (1.56:1.03, 1.39:1.04, P 0.0001) , The critical value is 1.29 or 1.16. In the diagnosis of acute cholecystitis, two investigators observed an additional retrospective analysis of p SWE images showing that the subjects operating special
