摘　　要：目的研究股骨头缺血性坏死(ANFH)的分期,早期影像学表现及诊断价值。方法回顾性分析40例的60个股骨头经临床证实为早期缺血性坏死的X线,CT及MRI影像学改变,并进行对比研究。结果在40例60个股骨头缺血性坏死中,双侧22例,单侧16例,依据FICAT分期,I期42例,II期18例,X片检查均为阴性,CT检查部分阳性。结论在临床上凡是有髋部疼痛,功能障碍,长期饮酒及大量长期应用糖皮质激素者,都应进行MRI检查,力求早期诊断。Objective To study the staging and diagnosis of early avascular necrosis of femoral head (ANFH) with MRI.Methods MRI findings and stages of 60 early ANFH in 40 patients proved by pathology were analyzed retrospectively and compared with X- ray plainfilm and CT.Results MRI demonstrated that,among 60 early ANFH of 40 patients,22 were bilateral and 16 were unilateral.Based on FICAT classification,42 hips were referred to stage 1 and 18 were referred to stage Ⅱ .All results of X- ray plainfilm were negative while the results of CT were partially positive.Conclusion In order to make the diagnosis of early ANFH MRI should be done in patients who explain hip pains and disfunction as well as have a long history of drinking alcohol and of administration of steroids.
