CT和核磁共振诊断股骨头坏死的临床对比

Clinical Comparison of CT and MRI in the Diagnosis of Necrosis of the Femoral Head

目的对比CT和核磁共振(MRI)诊断股骨头坏死的临床效果。方法随机抽取黑龙江省农垦总局总医院放射科于2016年8月—2017年10月收治的98例股骨头坏死患者为研究对象。随机将其均匀分成对照组(49例)和观察组(49例)。分别给予两组患者CT检查、MRI检查,观察患者的分期结果、早期阳性征象检出率。结果观察组患者的分期准确率、早期阳性征象检出率均高于对照组,差异有统计学意义(P<0.05)。结论与CT诊断相比,MRI诊断对股骨头坏死患者的分期准确率、早期阳性征象检出率均相对较高。

Objective To compare CT and nuclear magnetic resonance （MRI） in clinical diagnosis of femoral head necrosis. Methods 98 cases of osteonecrosis of the femoral head treated from August 2016 to October 2017 were randomly selected from the department of radiology of the general hospital of heilongjiang provincial general administration of agriculture and reclamation. They were randomly divided into control group （49 cases） and observation group （49 cases）. The patients were given CT examination, MRI examination, early stage results, the positive signs detection rate was recorded. Results The accuracy rate of the patients in the observation group and the positive rate of early positive signs were higher than those in the control group, the difference was statistically signifcant （P 〈 0.05）. Conclusion Compared with CT diagnosis, MRI diagnosis and accurate staging rate of femoral head necrosis in patients with positive signs, early detection rates are relatively high.
