In a comparison of conventional and magnetic resonance (MR) angiography of the lower extremities, MR imaging was performed with extremity and body coils and a unilateral six-coil telescopic phased-array coil. In one of seven volunteers, average signal-to-noise ratio was 140% higher with the latter (p < .01), only three of five stations were necessary, and examination time was decreased 50%. In the four patients, correlation in findings was 100%.
在一项下肢传统血管造影与磁共振（MR）血管造影的对比研究中，采用肢体线圈、体部线圈及单侧六线圈可伸缩相控阵线圈进行MR成像。在7名志愿者中的1名身上，使用后者时平均信噪比提高了140%（p < 0.01），仅需对5个部位中的3个进行检查，且检查时间缩短了50%。在4名患者中，检查结果的相关性为100%。
