分析股骨头坏死患者应用CT与核磁共振的临床诊断价值

Analysis of the clinical value of CT and MRI in the diagnosis of femoral head necrosis

目的:探讨早期股骨头坏死患者应用CT与核磁共振的诊断学价值。方法:选取2018年7月—2019年9月期间在我院就诊的早期股骨头坏死患者82例,依据随机数字表法将其分为研究组和参照组,每组各41例。研究组患者实施核磁共振诊断方式,参照组患者则实施CT诊断方式。对比分析两组患者的诊断结果,包括患者的确诊率、阳性率以及阴性率。结果:参照组患者进行CT诊断后,其患者疾病早期确诊率明显低于研究组患者,研究组患者经过核磁共振诊断后的阴性率为24.3%,显著低于参照组患者的阴性率73.1%。研究组患者经过核磁共振诊断后的阳性率为61.1%,显著高于参照组患者的阳性率36.6%。两组之间的结果对比差异明显,统计学意义存在(P<0.05)。结论:早期股骨头坏死患者应用CT与核磁共振的临床诊断价值差异悬殊,核磁共振的诊断效果较好,诊断确诊率、阳性率以及阴性率的准确程度显著高于CT检测,且适用于临床股骨头坏死患者的临床诊断。

Objective To explore the value of CT and MRI in the diagnosis of early necrosis of the femoral head.Methods From July 2018 to September 2019,82 patients with osteonecrosis of the femoral head were selected and divided into study group and reference group according to the method of random number table,41 cases in each group.The patients in the study group were diagnosed by MRI,while those in the reference group were diagnosed by CT.The diagnosis results of the two groups were compared,including the diagnosis rate,positive rate and negative rate.Results After CT diagnosis,the diagnosis rate of the patients in the reference group was significantly lower than that in the study group.The negative rate of the patients in the study group after MRI diagnosis was 24.3%,which was significantly lower than that in the reference group(73.1%).The positive rate of MRI in the study group was 61.1%,significantly higher than that in the reference group(36.6%).There was significant difference between the two groups(P<0.05).Conclusion There is a great difference between CT and MRI in the clinical diagnosis of femoral head necrosis.The diagnostic effect of MRI is better.The accuracy of the diagnostic rate,positive rate and negative rate is significantly higher than that of CT,and it is suitable for the clinical diagnosis of femoral head necrosis.
