【摘要】：目的观察坐骨股骨撞击综合征(IFI)患者MRI影像学征象,探讨磁共振横断面不同测量指标对IFI的诊断价值。方法回顾性分析行髋关节MRI检查,确诊为IFI的32例患者(共62个髋关节)资料,作为病例组;另搜集29例排除IFI的患者共58个髋关节资料,作为对照组;在横断面T_1WI TSE序列像上测量坐骨股骨间隙(IFS)、股方肌间隙(QFS)、股方肌总体积(TQFMV)及乆绳肌腱面积(HTA)。结果病例组患者的IFS、QFS、TQFMV分别为(11.5±3.3)mm、(6.6±2.2)mm、(17.2±6.3)cm~3;对照组上述指标分别为(22.5±3.8)mm、(14.6±3.3)mm、(25.1±5.6)cm~3。上述各组数据病例组均小于对照组,差异有统计学意义(t值分别为-17.0,-16.53,-6.9;P值均0.05)。病例组HTA值为(2.9±0.5)cm~2,对照组HTA值为(2.0±0.4)cm~2,病例组HTA大于对照组,差异有统计学意义(t值为9.8,P0.05);病例组IFS与QFS、TQFMV间存在正相关关系(r值分别为0.833、0.687;P值均0.05);HTA与QFS、TQFMV之间存在负相关关系(r值分别为-0.634、-0.815;P值均0.05);IFS、QFS、TQFMV及HTA诊断界值分别为≤15.4、≤7.1、≤17.86、≥2.56;病例组患者水肿及脂肪浸润不同等级相应IFS之间差异不具有统计学意义(P0.05)。结论 MRI检查发现IFS、QFS狭窄及股方肌水肿或脂肪浸润对诊断IFI有极其重要的诊断价值,可为临床诊断IFI、制定治疗方案及选择手术方式提供有力凭证。
[Abstract]:Objective to observe the imaging features of MRI in patients with sciatic femur impingement syndrome (IFI), and to evaluate the diagnostic value of different MRI cross-sectional measurements in IFI. Methods the hip joint MRI was retrospectively analyzed. Thirty-two patients (62 hips) diagnosed as IFI were selected as case group, and 58 hip joint data were collected from 29 patients who excluded IFI as control group. On the T 1WI TSE images of the patients, we measured the IfSV, the total volume of the quadratus femoris, the total volume of the quadratus femoris and the area of the tendons. Results the TQFMV of the patients in the case group were 11.5 卤3.3mm, 6.6 卤2.2mm and 17.2 卤6.3mm / cm ~ (-1) respectively, and the above indexes in the control group were 22.5 卤3.8mm ~ (14.6 卤3.3mm) ~ 14.6 卤3.3mm ~ (-1) 卤5.6mm ~ (-1) 路cm ~ (-1), respectively. The data of the patients in the control group were as follows: 22.5 卤3.8mm ~ 14.6 卤3.3mm ~ (-1) 卤5.6mm ~ (-1) 路cm ~ (-1). The case group was smaller than the control group. The difference was statistically significant (P < 0. 05). The HTA value in the case group was 2. 9 卤0. 5 cm ~ (-2), and the HTA value in the control group was 2. 0 卤0. 4 cm ~ (-2). The HTA in the case group was higher than that in the control group. The positive correlation between IFS and TQFMV was 0.833, 0.687P and 0.05P, respectively. The negative correlation between IFS and TQFMV was -0.634- 0.815P, and the diagnostic limit of HTA was 鈮，
