摘　　要：目的分析MRI测量股骨头坏死塌陷前期髋关节软骨的厚度及表观弥散系数。方法随机选取医院收治的2013年1月到2015年1月60例经影像学检查诊断为股骨头坏死塌陷前期的患者,并且将其作为研究组(60例);同时,选择同期60例行盆腔扫描的无髋关节症状的非股骨头坏死的成年人,将其作为对照组(60例);针对临床两组进行MRI测量,分析股骨头坏死塌陷前期患者髋关节软骨厚度以及其表观弥散系数(ADC),为预测股骨头塌陷提高观察指标。结果对两组进行MRI测量发现,在股骨头坏死塌陷前期,对照组成年人髋关节软骨ADC均值为(10.89±1.66)×10-5mm2/s,软骨厚度为1.9mm;研究组髋关节软骨ADC均值为(15.23±4.72)×10-5mm2/s,塌陷前期髋关节软骨厚度为1.2mm,两组软骨厚度以及表观弥散系数存在差异,研究组与对照组比较具有统计意义(P<0.05)。结论在临床股骨头坏死诊断中,应用MRI测量髋关节软骨的厚度、表观弥散系数,对关节软骨反应灵敏,可以有效预测早期股骨头坏死塌陷,为临床软骨病变诊断提供参考标准。Objective To analysis the MRI measured pre collapse osteonecrosis of the hip cartilage thickness and apparent diffusion coefficient. Methods 60 cases of hospital from 2013 January to 2015 1 menstrual imaging diagnosis for early avascular necrosis of femoral collapse in patients, as well as the study group（60 cases）; at the same time, 60 cases of pelvic scan without hip symptoms non avascular necrosis of the femoral head in adults, as the control group（60 cases）; MRI measurement for the two clinical groups avascular necrosis of the femoral head collapse, in patients with hip cartilage thickness and the apparent diffusion coefficient（ADC）, for the prediction of femoral head collapse to improve the observation index. Results two groups of MRI measurement, in avascular necrosis of the femoral head collapse early in the study group, the control group of normal adult articular cartilage mean ADC（10.89±1.66）×10-5mm2/s, the thickness of articular cartilage; articular cartilage of group mean ADC（15.23±4.72）×10-5mm2/s, stage of hip the thickness of articular cartilage was 1.2mm, two groups of cartilage thickness and apparent diffusion coefficient are different, the study group compared with the control group, with statistical significance（P〈0.05）. Conclusion In the clinical diagnosis of femoral head necrosis, measurement of articular cartilage using MRI thickness, apparent diffusion coefficient, on articular cartilage of sensitive reaction, can effectively predict the early avascular necrosis of the femoral head collapse, and provide reference standard for clinical diagnosis of articular cartilage lesions.
