摘　　要：目的分析髋关节撞击综合征(FAI)DR、MRI影像表现特征。方法收集本院2019年1月至2020年4月收治的147例经手术证实为FAI患者的临床资料。对患者所得DR、MRI图像进行分析,总结FAI患者影像表现特征。结果在DR图像中,147例患者均可见有不同程度的“枪柄样”畸形存在,有71例患者可见其髋臼后倾且髋臼过深,髋臼“交叉”征为阳性,存在“8字”征;12例患者存在非圆形股骨头,72例患者髋臼边缘软骨下可见囊性变;29例患者则是股骨头颈交界处皮质下有囊性病变存在。MRI检查图像中,所有患者髋臼盂唇均存在不同程度损伤;MRI分型:ⅠB、ⅡA期,分别有48例、39例,其余ⅠA期29例、ⅡB期25例、ⅢA期6例。患者α角值为58°~78°平均值为(65.89±7.63)°。结论股骨头颈解剖学异常及髋臼形态异常是FAI的主要征象,DR可作为临床筛选检查,结合MRI综合评价可有效降低FAI漏诊率。Objective To analyze the characteristics of DR and MRI images of femoroacetabular impinge-ment syndrome(FAI). Methods The clinical data of 147 patients who were treated in our hospital from January 2019 to April 2020 and were diagnosed as FAI by surgery were collected. The DR and MRI images of the patients were analyzed, and the imaging characteristics of FAI patients were summarized. Results In the DR image, 147 patients were found to have different degrees of "handlelike" deformities, and 71 patients have acetabular retroversion and deep acetabulum, and the acetabular "cross" sign was positive, and the "8" sign was present. 12 patients had non-circular femoral heads, 72 patients had cystic changes under the acetabular marginal cartilage. In 29 patients,there was a cystic lesion under the cortex of the junction of the femoral head. In the MRI images, all patients had different degrees of damage of acetabular labrum. MRI classification: there were 48 cases were in IB stage and 39 cases were in IIA respectively, 29 cases in ⅠA stage, 25 cases in ⅡB stage and 6 cases in stage ⅢA. The alpha value of the patient was 58°-78°, and the average value was(65.89 ±7.63)°. Conclusion The anatomical abnormalities of the femoral head and neck and the morphological abnormalities of the acetabulum are the main signs of FAI. DR can be used as a clinical screening test. It was combined with the damage of acetabular labrum and articular cartilage displayed by MRI,comprehensive evaluation can effectively reduce the missed diagnosis rate of FAI.
