股骨头缺血性坏死应用核磁诊断的效果分析

Analysis of the Effect of NMR Diagnosis on Avascular Necrosis of the Femoral Head

目的分析股骨头缺血性坏死应用核磁诊断的效果。方法选取90例股骨头缺血性坏死患者,随机分为CT组与核磁组各45例,分别应用CT与核磁进行诊断,对比病理结果,分析两种诊断方法的应用效果。结果 CT组检出率为75.6%,核磁组检出率为91.1%,核磁组高于CT组,对比差异有统计学意义(P<0.05)。CT组检出Ⅰ期8例,Ⅱ期16例,Ⅲ期7例,Ⅳ期3例;核磁组检出Ⅰ期11例,Ⅱ期19例,Ⅲ期8例,IV期3例;核磁组Ⅰ期、Ⅱ期的检出率高于CT组,对比差异有统计学意义(P<0.05)。结论股骨头缺血性坏死应用核磁诊断的效果显著。

Objective To analyze the effect of NMR diagnosis on avascular necrosis of the femoral head. Methods 90 cases of avascular necrosis of the femoral head were randomly divided into CT group and NMR group, 45 cases in each group, and were diagnosed by CT and NMR, respectively. In contrast to the pathological results, the application of the two diagnostic methods was analyzed. Results The detection rate in group CT was 75.6%, the detection rate of NMR group was 91.1%, NMR group was higher than that of CT group, and the difference was statistically signifcant （P 〈 0.05）. In group CT, 8 cases were detected in I phase, 16 cases in II phase, 7 in III stage and 3 in IV stage. In the NMR group, 11 cases were detected in I stage, 19 cases in II phase, 8 in III phase and 3 in IV stage. The detection rate of I phase and II phase in NMR group was higher than that in group CT, and the difference was statistically significant （P 〈 0.05）. Conclusion The effect of NMR diagnosis on avascular necrosis of the femoral head is signifcant.
