摘要
目的：探讨多排螺旋 CT 与 MRI 检查股骨头坏死临床价值。方法抽取2014年2月-2016年2月我院接收的62例股骨头坏死患者，根据入院先后顺序分为研究组与对照组，各31例。研究组行 MRI 检查，对照行多排螺旋 CT 检查。对比两组阳性检出率及早期阳性征象检出率。结果研究组股骨头坏死阳性检出率为93.55%、单一馕变检出率为96.77%、线样征检出率为64.52%、骨髓水肿检出率为74.19%、骨小梁结构模糊检出率为77.42%，对照组股骨头坏死阳性检出率为为70.97%、单一馕变检出率为74.19%、线样征检出率为19.35%、骨髓水肿检出率为22.58%、骨小梁结构模糊检出率为32.26%，组间比较差异显著（P ＜0.05）。结论应用 MRI 检查股骨头坏死检出率较高，且软组织分辨率高，可清晰呈现骨质坏死处解剖形态。
Objective To investigate the clinical value of multi-slice spiral CT and MRI in the treatment of femoral head necrosis. Methods 62 patients with femoral head necrosis received in our hospital from February 2014 to February 2016 were selected. According to the order of admission, the patients were divided into study group and control group, with 31 cases in each group. The study group was examined by MRI, and the control group was examined by multi slice spiral CT. The positive detection rate and early positive signs were compared between the two groups. Results The study group of avascular necrosis of the femoral head positive detection rate was 93.55%, single Nang changes detection rate was 96.77%, line like sign incidence was 64.52%, bone marrow edema detection rate was 74.19%and bone trabecula structure fuzzy detection rate was 77.42%.The control group of avascular necrosis of the femoral head positive detection rate for 70.97%, single Nang changes detection rate for 74.19% and line like sign incidence for 19.35%, bone marrow edema detection rate was 22.58%, trabecular structure fuzzy detection rate was 32.26%, the difference between groups was significantly （P〈0.05）. Conclusion The detection rate of necrosis of femoral head with MRI is high, and the soft tissue resolution is high, which can clearly show the anatomical morphology of bone necrosis.
