摘要/Abstract

摘要： 本研究主要探讨高场强MRI和彩色多普勒超声参数对梨状肌综合征的诊断价值。选取2017年6月~2019年6月本院收治且已临床确诊的31例梨状肌综合征患者作为观察组，选取同期于本院体检的健康人群31例作为对照组，高场强MRI检测坐骨神经信号强度及肌肉信号强度，彩色多普勒超声检测梨状肌厚度和坐骨神经厚度。结果显示，观察组患侧梨状肌厚度显著高于对照组（P<0.05），患侧序列T2WI的神经信号强度/肌肉信号强度显著高于对照组（P<0.05），梨状肌厚度、神经信号强度/肌肉信号强度诊断梨状肌综合征的曲线下面积（AUC）分别为0.836、0.869，二者联合诊断梨状肌综合征的AUC为0.945。高场强MRI和彩色多普勒超声均有一定的诊断价值，且彩色多普勒超声对梨状肌综合征患者检出率更高，两者联合可进一步提高梨状综合征的诊断价值。

Abstract: The purpose of this study was to investigate the value of high field MRI and color Doppler ultrasound in the diagnosis of piriformis syndrome. From June 2017 to June 2019, 31 patients with piriformis syndrome who were admitted to our hospital and diagnosed clinically were selected as the observation group; 31 healthy people who were examined in our hospital at the same time were selected as the control group. The signal intensity of sciatic nerve and muscle was detected by high field MRI, and the thickness of piriformis and sciatic nerve was detected by color Doppler ultrasound. The results showed that the thickness of piriformis muscle in the observation group was significantly higher than that in the control group (P<0.05). The nerve signal strength/muscle signal strength of T2WI of the affected side was signficantly higher than that of control group (P<0.05). The area under curve (AUC) of piriformis muscle thickness and nerve signal intensity/muscle signal intensity in the diagnosis of piriformis syndrome was 0.836 and 0.869, respectively. the AUC of the two combined diagnosis of piriformis syndrome was 0.945. High field MRI and color doppler ultrasound have certain diagnostic value, and the detection rate of color Doppler ultrasound is higher in patients with piriformis syndrome. The combination of the two can further improve the diagnostic value of piriformis syndrome.
