成人早期股骨头缺血坏死比较影像学研究

Iconography Study on Early Ischmic Necrosis of Femoral Head of Adults

目的比较三种(X线平片、CT、MRI)影像学检查方法,对成人早期股骨头无菌坏死的诊断价值,提高早期诊断水平。方法筛选临床及影像学检查资料齐全已确诊的病例36例、48个髋关节早期缺血坏死的X线平片、CT、MRI的诊断结果,进行回顾性的分析研究,比较三种检查方法的诊断结果。结果48个早期股骨头缺血坏死中,I期17髋,II期31髋,早期(I～II期)股骨头坏死的X线平片、CT及MRI的诊断确诊率分别33.33%、62.50%及100.00%。结论MRI是诊断早期股骨头缺血坏死最敏感、最有效的方法,优于CT和X线平片,是早期高危患者筛查的首选方法。

Objective To compare three kinds iconography examination （X-ray,CT,MRI）, discuss the diagnostic value for early ischmic necrosis of femoral head of adults, and to raise the diagnostic level in early days. Methods To analyse retrospectively 36 patients which have complete clinical and iconography examination data, and to make a definite diagnosis, including 48 articulatio coxaes＇ earlier period diagnosis data of the X-ray, CT, MRI. Results In 48 articulatio coaxes with earlier period femoral head ischer, lia necrosis, the Ⅰ stage 17 hips and the Ⅱ stage 31 hips, the positive diagnostic rates of the X-ray, CT and MRI in earlier period （Ⅰ -Ⅱ stage）femoral head were 33.33%, 62.50% and 100.00%. Conclusion MRI is the most diagnostic method, it＇s sensitive and effective for the earlier period femoral head surpass, overmatch CT and the X-ray. MRI is the preferred method of for high risk patients which ischemic necrosis of femoral head in early days.
