摘　　要：目的探讨股骨与坐骨撞击相关综合征的磁共振成像(MRI)图像表现。方法选择股骨与坐骨撞击综合征(IFIS)病例组40例及对照组40例均行MRI的扫描;在横轴位的T1加权成像(T1WI)TSE序列测量股骨和坐骨之间的间距(IFS),股方肌间的间距(QFS),在横轴位的PDWI SPAIR序列上评估股方肌的水肿程度;所得测量数据分别采取t检验、Pearson相关性及单因素方差分析进行比较。结果IFIS组与对照组IFS及QFS差异均具有统计学意义(P<0.05)。IFIS组的IFIS(12.2±2.5)mm与QFS(8.8±2.2)mm小于对照组IFS(26.9±5.3)mm及QFS(22.7±4.8)mm,而且IFS与QFS呈正相关性(r=0.847,P<0.05);股方肌水肿的不同分级之间IFS差异具有统计学意义(F=10.21,P<0.01)。结论IFS、QFS变窄,股方肌的水肿是MRI诊断IFIS的重要征象。Objective To explore the MRI imaging signs of ischi-femoral impingement syndrome.Methods Retrospectively analyze 44 cases with IFIS as the case group and the other 40 patients as the control group by MRI scanning.The ischial femoral space(IFS),and quadratus femoris space(QFS)were measured on axial T1WI.To evaluate the degree of edema and fat infiltration of the quadratus femoris muscle on coronal PDWI SPAIR.The data was tested by using the t-test,Pearson correlation,and ANOVA test.Results The differences in IFS and QFS between the IFIS group and the control group were statistically significant(P<0.05).In the IFIS group,the IFS width,QFS width(12.2±2.5)mm,(8.8±2.0)mm were lower than those in control group[(26.9±5.3)mm VS(22.7±4.8)mm]and there was a positive correlation between IFS and QFS(r=0.847,P<0.05).The differences in IFS width among different grades of femoral quadratus edema in IFIS patients were statistically significant(both P<0.05).Conclusion The narrowing of IFS and QFS,and changes in quadratus femoris morphology and signal are important indicators for MRI diagnosis of IFIS.
