摘　　要：目的对比分析磁共振成像(magnetic resonance imaging,MRI)、多排螺旋CT对成人股骨头坏死经皮置管术介入前后影像学特征。方法选取2019年1至12月在温州市人民医院行经皮置管术介入治疗的成人股骨头坏死患者54例,采用西门子Siemens1.5T磁共振扫描仪对患者进行MRI扫描,采用飞利浦MX4000Dual通道螺旋CT对患者进行扫描,并分析患者经皮置管术介入前后影像学特征。结果MRI检查成人股骨头坏死患者分期检出率明显高于多排螺旋CT检查,差异有统计学意义(P<0.05)。MRI检查关节囊钙化、关节囊肿胀、股骨头韧带钙化、肌肉萎缩、髂腰肌囊扩张检出率明显高于多排螺旋CT检查,差异有统计学意义(P<0.05)。与多排螺旋CT检查比较,MRI检查对成人股骨头坏死的敏感度、特异性、准确性较高,差异有统计学意义(P<0.05)。结论多排螺旋CT与MRI联合检查对成人股骨头坏死的诊断价值更高,且经皮置管术对患者有较好的疗效。Objective To analyze the imaging features before and after percutaneous catheterization intervention by MRI scan and multirow spiral CT on adult femoral head necrosis.Methods A total of 54 adult patients with femoral head necrosis undergoing interventional therapy by percutaneous catheterization in Wenzhou People’s Hospital from January to December 2019.all the patients were scanned by MRI using a Siemens.5T MRI scanner and by CT scan using a Philips MX4000Dual channel spiral CT.The imaging characteristics of the patients before and after percutaneous catheterization intervention were also analyzed.Results Compared with multi-slice spiral CT,MRI examination of adult patients with femoral head necrosis staging detection rate increased,the difference was statistically significant(P<0.05).Compared with multi-slice spiral CT,the detection rate of joint capsule calcification,joint cyst expansion,femoral head ligament calcification,muscle atrophy and iliopsoas muscle sac expansion were increased,the difference was statistically significant(P<0.05).Compared with MSCT,MRI had higher sensitivity,specificity and accuracy in adult femoral head necrosis(P<0.05).Conclusion The combination of multiple-row spiral CT and MRI has a high diagnostic value of femoral head necrosis in adults,and percutaneous catheterization has a good effect in patients.
