本研究的目的是确定CT血管成像生理盐水自动触发不同注射速率时对主动脉的强化作用。利用生理流动模型进行单层动态CT扫描,扫描时间为开始注射对比剂后0~50 s。对比剂注射方式相同(150 mL,注射速率5 mL/s),以4
The purpose of this study was to determine if the CT angiographic saline solution automatically potentiates the aorta enhancement at different injection rates. Single-layer dynamic CT scans were performed using a physiological flow model with a scan time from 0 to 50 s after the start of contrast injection. Contrast injection in the same way (150 mL, injection rate 5 mL / s) to 4
