目的:分析CT与磁共振技术在股骨头坏死诊断中的应用价值。方法:抽取2014年5月至2015年12月在我院接受治疗的股骨头坏死患者81例,随机分组,对照组40例,观察组41例,对照组实施CT检测,观察组实施磁共振(MRI)检测,观察比较两组阳性检出率及分级情况。结果:观察组阳性检出率为80.49%(33/41),对照组为60.00%(24/40),观察组阳性检出率高于对照组,差异具有统计学意义(P<0.05);Ⅰ期、Ⅱ期组间比较,差异无统计学意义(P>0.05),观察组Ⅲ期、Ⅳ期均高于对照组,差异具有统计学意义(P<0.05)。结论:磁共振技术应用于股骨头坏死诊断中较CT检测,检出率更高,且分级更准确,可作为诊断股骨头坏死的依据。
Objective: To analyze the value of CT and magnetic resonance imaging in the diagnosis of osteonecrosis of the femoral head. Methods: Totally 81 patients with femoral head necrosis treated in our hospital from May 2014 to December 2015 were randomly divided into control group (n = 40) and observation group (n = 41). CT was performed in the control group and magnetic resonance imaging MRI) detection, observation and comparison of the positive detection rate and grading of the two groups. Results: The positive rate was 80.49% (33/41) in the observation group and 60.00% (24/40) in the control group, and the positive rate in the observation group was higher than that in the control group (P <0.05). There was no significant difference between stage Ⅰ and stage Ⅱ (P> 0.05). Stage Ⅲ and stage Ⅳ of the observation group were higher than that of the control group, with statistical significance (P <0.05). Conclusion: MRI is more effective than CT in the diagnosis of osteonecrosis of the femoral head. The detection rate is higher and the grading is more accurate. It can be used as the basis to diagnose the femoral head necrosis.
