目的探讨CT检查和核磁共振检查诊断股骨头坏死的准确性。方法选择我院2015年1月-2016年1月收治的75例股骨头坏死患者,所有患者均行CT和核磁共振检查,观察两组检查结果,就其准确率展开分析。结果 CT检查结果显示,75例患者中被确诊为股骨头坏死的69例,误诊6例,准确率92%。经核磁共振检查结果显示,75例患者中被确诊为股骨头坏死的75例,误诊0例,准确率100%。两组比较差异有统计学意义(P<0.05)。结论相较于CT扫描诊断,核磁共振检查诊断股骨头坏死的准确性更高,不但能帮助医师判断患者病情,更能为治疗预后提供有效依据,值得推广。
Objective To investigate the accuracy of CT and MRI in diagnosing femoral head necrosis. Methods Seventy-five patients with femoral head necrosis admitted to our hospital from January 2015 to January 2016 were enrolled in this study. All patients underwent CT and MRI examinations. The results of the two groups were observed and their accuracy was analyzed. Results CT examination showed that in 75 patients were diagnosed as osteonecrosis of the 69 cases, 6 cases were misdiagnosed, the accuracy rate of 92%. The results of MRI showed that 75 cases were diagnosed as avascular necrosis in 75 cases, misdiagnosis in 0 cases, the accuracy rate of 100%. The difference between the two groups was statistically significant (P <0.05). Conclusion Compared with CT scan diagnosis, MRI diagnosis of higher accuracy of femoral head necrosis, not only can help physicians determine the patient’s condition, but also provide an effective basis for the treatment of prognosis, it is worth promoting.
