The value of CTA in the diagnosis of accessory renal artery / 实用放射学杂志

ABSTRACT

Objective To evaluate the clinical application value of CT angiography(CTA) in detection of the accessory renal artery(ARA).Methods The renal artery CTA in 100 cases was reconstructed retrospectively with volume rendering (VR), multiplanar reconstruction (MPR), maximum density projection (MIP) and curved surface reconstruction (CPR).Results In all 200 kidneys,ARA were 47 with an incidence of 23.5% (47/200).The incidence of ARA in male and female were about 17% and 13%, and there was no significant difference between them.The ARA in the upper pole of the kidney was 25 (53.1%), and in lower pole was 22 (46.9%).It was showed on MIP with a display rate of 100%, on MRP of 93.6%, on VR of 90.4% and on CPR of 85.1%.Conclusion CTA is a safe, rapid, noninvasive and economical method for the diagnosis of ARA.It is helpful for surgical renal operation, interventional therapy and renal transplantation.
