目的对比分析早期成人股骨头缺血性坏死的DR、CT和MRI影像学检查的表现。方法回顾分析本院2016年9月至2017年7月实施诊治的67例早期成人股骨头缺血性坏死患者的临床诊断资料,全部患者均于同期分别进行DR、CT和MRI影像学检查,对比观察这三种方法的影像诊断结果,以总结其影像学表现的不同。结果对比DR、CT、MRI三种影像学对67例早期成人股骨头缺血性坏死的诊断结果表明,MRI的确诊率为最高(97.01%),其次为CT(80.60%),最低的为DR(55.22%),对三种诊断结果进行两两对比,其差异有统计学意义(P<0.05)。结论在对早期成人股骨头缺血性坏死患者进行临床诊断时,MRI相对于DR与CT而言,可所获更高的确诊率,若患者及医院条件允许的情况下,可优先应用MRI影像学检查进行临床诊断。
Objective To compare and analyze the manifestations of DR, CT and MRI imaging of avascular necrosis of femoral head in early adults. Methods The clinical data of 67 patients with early avascular necrosis of the femoral head treated in our hospital from September 2016 to July 2017 were retrospectively analyzed. All patients underwent DR, CT and MRI imaging examinations in the same period. The diagnostic results of these three methods were observed to summarize the differences in their imaging findings. Results The diagnosis of ischemic necrosis of the femoral head in 67 cases of early adults showed that MRI was the highest (97.01%), followed by CT (80.60%), the lowest was DR (55.22%). The results of the three kinds of diagnosis were compared in any pairwise and the difference was statistically significant (P <0.05). Conclusions In the clinical diagnosis of early adult patients with avascular necrosis of the femoral head, the relative diagnostic yield of MRI compared with that of DR and CT may be higher. If the patient and the hospital are allowed, the MRI image may be used preferentially School examinations for clinical diagnosis.
