CT与MRI诊断股骨头坏死的价值研究

Diagnostic Value of CT and MRI in the Diagnosis of Femoral Head Necrosis

目的对比CT检查与MRI检查对股骨头坏死的诊断价值。方法选取2016年5月～2018年5月医院门诊收治的78例股骨头坏死患者作为研究对象,依据检查方式不同将患者分为对照组38例和观察组40例。对照组患者行双侧股骨头CT检查,观察组患者行MRI检查,比较两组的诊断结果。结果观察组患者确诊率高于对照组(97.50%vs 78.95%),差异有统计学意义(P<0.05);观察组患者Ⅰ期、Ⅱ期、Ⅲ期、Ⅳ期的诊断率均高于对照组,其实Ⅰ期、Ⅳ期比较,差异有统计学意义(P均<0.05),Ⅱ期、Ⅲ期比较,差异无统计学意义(P>0.05)。结论 MRI检查对股骨头坏死患者的诊断准确率较高,优于CT检查,可用于临床早期诊断中。

Objective To compare the diagnostic value of CT and MRI in femoral head necrosis. Methods From May 2016 to May 2018, 78 patients with femoral head necrosis were selected and divided into control group （38 cases） and observation group （40 cases） according to different examination methods. The patients in the control group were examined with bilateral femoral head CT, the patients in the observation group were examined with MRI, and the diagnostic results of the two groups were compared.Results The diagnostic rate of the patients in the observation group was significantly higher than that in the control group （97.50% vs 78.95%）,the difference was statistically significant （P〈0.05）.The diagnostic rates of stage Ⅰ, Ⅱ, Ⅲ and Ⅳ in the observation group were higher than those in the control group,the difference between stage Ⅰ and stage Ⅳ was statistically significant （P〈0.05）, but there was no significant difference between stage Ⅱ and stage Ⅲ （P〉0.05）.Conclusion MRI examination has a higher diagnostic accuracy for patients with femoral head necrosis, which is superior to CT examination and can be used in early clinical diagnosis.
