核磁诊断股骨头缺血性坏死的临床应用价值

Clinical Value of MRI in Diagnosis of Avascular Necrosis of Femoral Head

目的:为了分析核磁诊断股骨头缺血性坏死的临床应用价值,为临床诊疗工作提供借鉴。方法:选取2019年3月~2020年3月在本院进行治疗的53例股骨头缺血性坏死患者为研究对象,所有患者均经过手术病理确诊。对这53例骨头缺血性坏死患者分别进行核磁共振检查和CT检查,将诊断结果分别记为研究组和对照组,观察观察两组诊断结果的病变检出率。结果:CT诊断早期股骨头缺血性坏死患者13例,中晚期股骨头缺血性坏死患者29例,总病变检出率为79.25%(42/53);核磁诊断早期股骨头缺血性坏死患者26例,中晚期股骨头缺血性坏死患者27例,总病变检出率为100.00%(53/53),组间差异显著(P<0.05)。结论:相比CT技术核磁在股骨头缺血性坏死诊断中具有更高的诊断准确率。

Objective:To analyze the clinical application value of MRI in the diagnosis of avascular necrosis of femoral head and provide reference for clinical diagnosis and treatment.Methods:53 patients with avascular necrosis of the femoral head treated in our hospital from March 2019 to March 2020 were selected as the research objects.MRI and CT were performed in 53 patients with avascular necrosis of the head,and the diagnosis results were recorded as the study group and the control group respectively.The detection rate of lesions in the two groups was observed.Results:The results of CT diagnosis showed that there were 13 cases of early avascular necrosis of femoral head and 29 cases of middle and late stage of avascular necrosis of femoral head.The detection rate of total lesions was 79.25%(42/53).The results of MRI diagnosis showed that there were 26 cases of early avascular necrosis of femoral head and 27 cases of middle and late stage of avascular necrosis of femoral head.The detection rate of total lesions was 100.00%(53/53).There was significant difference between the two groups(P<0.05).Conclusion:Compared with CT technology,MRI has higher diagnostic accuracy in the diagnosis of avascular necrosis of the femoral head.
