Objective:To evaluate the value of dynamic contrast-enhanced MRI(DCE-MRI)with hemorrheology in the detection of femoral perfusion in the early stage of steroid-induced avascular necrosis of femoral head(AvNFH)model.

• 目的:运用动态增强磁共振成像(DCE-MRI)的方法,并结合血液流变学指标评估早期激素性股骨头缺血坏死(AvNFH)模型不同时期的股骨头血流灌注状态,以探讨DCE-MRI在AvNFH早期诊断中的应用价值。
