摘要
目的:探讨股骨头缺血坏死(ANFH)的MRI表现及诊断。材料与方法:34例双侧髋关节行MRI检查,全部病例均行SET1WI,FSET2WI和T2WI+压脂,横轴位及冠状位扫描。结果:34例50髋中,双髋16例、单髋18例。综合影像学特点,依据Kukobo等五期分期标准,0期0髋,Ⅰ期21髋,Ⅱ期14髋,Ⅲ期9髋,Ⅳ期6髋。髋关节积液可见于股骨头缺血的各期,其积液量常与骨质破坏相一致。结论:MRI能够准确显示ANFH的范围、程度及信号特征,对ANFH能实现早期诊断及分期。
Ohjectiove:to sudy the characteristics of avascular necrosis of femoral head(ANFH)on MRI.Meterials and methocls:MR scanning of hip joint was performed using SE and FSE sequence,T1WI,T2WI and T2WI with inversion recovery scanning,both coronal and axial,were performed in patients.Results:50 Fifty hips in 34 cases with 16 hips bilateral and 18 unilateral,Acconding to the imaging findings,based on knkobo classification,21 hips were stageⅠ,14 hiips were stage Ⅱ,9hips were stageⅢ and 6 hips were stage Ⅳ,Conclusion:MRI was a useful and accurate method in the diagnosis of the early stage of ANFH.and its extent ,degree and lcey feature could be shown correctly on MRI.
