The abdominal aorta and renal, visceral, and iliac arteries were evaluated in 16 patients with three-dimensional Fourier transform imaging enhanced with gadopentetate dimeglumine. By imaging dynamically during the arterial phase of a 5-minute injection (0.2 mmol/kg), highly significant (P < .0001) preferential arterial enhancement (signal-to-noise ratio +/- standard deviation, 10 +/- 0.9), with minimal enhancement of the inferior vena cava (5.1 +/- 1.4) or background tissues (fat, 4.3 +/- 0.7; muscle, 2.4 +/- 0.5), was achieved in every patient. In six patients with angiographic and/or surgical correlation, 10 of 10 stenoses and two of two occlusions were correctly identified. No in-plane saturation or pulsatility artifact was identified in any of the 16 patients. In conclusion, dynamic imaging during the injection of gadopentetate dimeglumine is a promising technique for evaluation of the abdominal aorta and branch vessels.
对16例患者使用钆喷酸葡胺增强的三维傅里叶变换成像评估腹主动脉以及肾动脉、内脏动脉和髂动脉。在5分钟注射（0.2 mmol/kg）的动脉期进行动态成像，每位患者均实现了高度显著（P <.0001）的动脉优先强化（信噪比±标准差，10±0.9），而下腔静脉（5.1±1.4）或背景组织（脂肪，4.3±0.7；肌肉，2.4±0.5）的强化极少。在6例有血管造影和/或手术对照的患者中，10处狭窄中的10处以及2处闭塞中的2处均被正确识别。16例患者中均未发现平面内饱和或搏动伪影。总之，注射钆喷酸葡胺时的动态成像对于评估腹主动脉及其分支血管是一种很有前景的技术。
