摘　　要：目的:探讨MR增强血管造影(CE-MRA)显示肾动脉解剖变异的价值。方法:采用回顾性分析213例肾动脉CE-MRA检查图像,包括肾动脉变异的显示情况以及分型。结果:肾动脉变异分别占病例数和肾脏数的30.05%(64/213)和19.72%(84/426),其中肾动脉过早分支发生率为6.57%(28/426),副肾动脉变异发生率为13.15%(56/426)。女性肾动脉变异发生率小于男性,同一患者两侧肾动脉变异发生率无显著性差异。常见肾动脉解剖变异类型均有显示。结论:肾动脉的解剖变异可以通过动态增强MR血管造影准确显示。0bjective：To evaluate the category of the variations on bilateral renal artery and clinical significance with Contrast enhancement MR angiography（CE-MRA）.Methods：CE-MRA of 213 patients were retrospectively analyzed.The variations on bilateral renal artery were observed and classified.Results：According to the number of the main renal artery,the anatomy of renal artery was classified in details.The incidence of early branch of the main renal artery and accessory renal artery was 6.57%（28/426）and 13.15%（56/426）,respectively.Significant difference of variation incidence was found between male and female.No statistical difference of variation incidence was found between left and right kidney.Conclusion：Anatomical variations on renal artery can be showed clearly with CE-MRA.
