58例股骨头缺血坏死的MR检查分析

目的]探讨MRI在股骨头缺血坏死(ANFH)患者的早期诊断中的临床价值。方法]58例患者(71髋)均于临床行X线片及MRI检查,并将两种影像学检查方法的检出结果进行记录与比较。结果]X线的阳性检出率为36.62%(26/71),MRI的阳性栓出率为97.18%(69/71),X线1～2期检出数量(20髋)明显低于MRI(69髋),数据经统计学比较差异有统计学意义(P﹤0.05);3～4期检出数量(6髋vs7髋)方面两组差异无统计学意义(P﹥0.05)。结论]MRI对临床诊断ANFH具有较高的检出率,临床应掌握早期ANFH的影像学指征,为早发现早治疗提供依据。

ANALYSIS OF THE FEMORAL HEAD MR EXAMINATION AMONG 58 CASES OF AVASCULAR NECROSIS

Objective]To explore the MRI in avascular necrosis of the femoral head(ANFH)in patients with early diagnosis and its clinical value.Methods]58 patients(71 hips)in clinical X-ray and MRI examinations,and two kinds of imaging methods in the detection results were recorded and compared.Results]Radiographic positive rate was 36.62%(26/71),MRI positive picks out rate was 97.18%(69/71),X-ray 1-2 detectable quantities(20 hips)was significantly lower than that in MRI(69 hips),and there was significant difference between them(P﹤0.05);3-4 detectable quantities(in 6 hips VS7 hip)has no significant difference between the two groups(P﹥0.05).Conclusion]MRI for clinical diagnosis of ANFH has a higher detection rate,clinical should grasp the early ANFH imaging indications for early detection and early treatment to provide the basis.
