摘　　要：目的探讨核磁共振成像对股骨头缺血坏死介入治疗的价值、意义。方法搜集本科介入治疗病例50例，术前全部先行核磁共振检查，行超选择性插管并经导管进行局部药物治疗，记录相关资料。结果磁共振检查，对股骨头坏死进行确切分期，尤其STIR等序列检查在早期ANFH中，对微小的水分差和脂肪成分差就能产生对比度。MRI在ANFH早期诊断的阳性检出率约为80％～90％，50例患者根据Steinberg分期，其中Ⅰ期-Ⅳ期34例，Ⅴ期-VI16例。在介入治疗过程中，根据分期，对药物灌注量及灌注时间有了比较可靠的指导，大大缩短了曝光时间，同时提高了疗效。结论MRI能更敏感地检出早期ANFH，有利于提高股骨头坏死介入治疗的效率、减轻血管损伤和辐射危害。Objective Discuss MRIto ischemic necrosis femoral head interventional therapy value and significance. Methods：Collect undergraduate intervention treatment of 50 cases of cases, Preoperative all first nuclear magnetic resonance examination, Do super selective intubation catheter and the local drug therapy, Record related data. Results：MRI examination, to avascular necrosis of the exactly on installment, especially such as STIR sequence inspection in the early ANFH, for small water difference and fat ingredient difference. Can produce contrast. MRI in early diagnosis of ANFH positive detection rate is about 80 %- 90%, 50 patients Steinberg installment according to m, the stage Ⅰto Ⅳ period and an example, Ⅴ period - Ⅵ16 cases. In the intervention treatment process, according to the installment, the drug perfusion measure and filling time have more reliable guidance, greatly shorten the time of exposure, and at the same time improve the curative effect. Conclusion： MRI can be more sensitive detection early ANFH, be conducive to improving the avascular necrosis of the intervention treatment effi- ciency, reduce vascular injury and radiation hazard.
