OBJECTIVE
The purpose of this study was to evaluate the feasibility of a novel technique for fat-water separation to image the renal arteries without using a contrast agent.
CONCLUSION
Five healthy volunteers were imaged on a 3-T clinical MR scanner using the balanced steady-state free precession (SSFP) Dixon method. We were able to image the proximal renal arteries with high conspicuity within a 3-minute overall scanning time. The balanced-SSFP Dixon method shows potential for unenhanced MR angiography of the proximal renal arteries.
目的
本研究的目的是评估一种新型脂肪-水分离技术在不使用造影剂的情况下对肾动脉成像的可行性。
结论
5名健康志愿者在3T临床磁共振扫描仪上采用平衡稳态自由进动（SSFP）狄克逊法进行成像。我们能够在3分钟的总扫描时间内以高清晰度对近端肾动脉进行成像。平衡SSFP狄克逊法在近端肾动脉的非增强磁共振血管造影中显示出潜力。
