MRI与MSCT在坐骨股骨撞击综合征诊断中的应用价值分析

目的分析核磁共振成像(MRI)与多层计算机断层扫描(MSCT)在坐骨股骨撞击综合征诊断中的应用价值。方法回顾性收集2017年9月~2019年11月我院骨科收治的65例坐骨股骨撞击综合征患者的临床资料,所有患者均经手术治疗确诊,并且在术前均进行MRI和MSCT检查。比较MRI和MSCT对坐骨股骨撞击综合征患者的检出率及坐骨股骨间隙(IFS)、股方肌间隙(QFS)值、疾病相关指标、疾病相关病变影像征象检出率。结果MRI对坐骨股骨撞击综合征的检出率为92.31%,显著高于MSCT(78.46%,P=0.025)。MRI和MSCT对坐骨股骨撞击综合征患者健侧、患侧IFS和QFS值及股骨颈前倾角(FNA)、股骨小转子角(LTA)、股骨颈干角(CCD)、坐骨角(IA)值比较,差异均无统计学意义(P>0.05)。MRI和MSCT检测坐骨股骨撞击综合征患者健侧IFS和QFS值均显著高于患侧(P<0.05)。MRI对坐骨股骨撞击综合征患者关节面硬化的检出率(9.23%)低于MSCT(23.08%),对股方肌水肿和滑膜囊肿的检出率(66.15%和21.54%)高于MSCT(24.62%和6.15%,P<0.05)。结论MRI对坐骨股骨撞击综合征、组织水肿及囊肿的诊断检出率高于MSCT,对关节面硬化的诊断检出率低于MSCT,因此可将两种方法联合用于坐骨股骨撞击综合征的诊断。

Application value analysis of MRI and MSCT in diagnosis of ischiofemoral impingement syndrome

Objective To analyze the application value of magnetic resonance imaging(MRI)and Mustu-skuce spuval computed tomography(MSCT)in the diagnosis of ischiofemoral impingement syndrome.Methods The clinical data of 65 patients with ischiofemoral impingement syndrome admitted to the department of orthopaedics of our hospital from September 2017 to November 2019 were retrospectively collected.All patients were diagnosed by surgery and underwent MRI and MSCT examination before operation.The detection rate of ischiofemoral impingement syndrome patients with MRI and MSCT,and the detection rate of ischiofemoral space(IFS),quadratus femoris space(QFS),disease-related indicators and imaging signs of disease-related lesions were compared.Results The detection rate of ischiofemoral impingement syndrome by MRI was 92.31%,which was significantly higher than that by MSCT(78.46%,P=0.025).There was no significant difference between MRI and MSCT in the IFS and QFS values,femoral neck anteversion angle(FNA),femoral lesser trochanter angle(LTA),femoral neck stem angle(CCD)and ischial angle(IA)of patients with ischiofemoral impingement syndrome(P>0.05).The values of IFS and QFS in healthy side were significantly higher than those in affected side by MRI and MSCT(P<0.05).The detection rate of articular surface sclerosis(9.23%)of MRI in patients with ischiofemoral impingement syndrome was lower than that of MSCT(23.08%),and the detection rates of quadratus femoris edema and synovial cyst(66.15% and 21.54%)were higher than those of MSCT(24.62%and 6.15%,P<0.05).Conclusion The diagnostic detection rate of MRI for ischiofemoral impingement syndrome,tissue edema and cyst is higher than that of MSCT,and the diagnostic detection rate of articular surface sclerosis is lower than that of MSCT.Therefore,the two methods can be combined for the diagnosis of ischiofemoral impingement syndrome.
