在16名志愿者中优化并评价了体积靶向造影剂增强屏气冠状动脉磁共振血管造影技术。在增强图像上观察到冠状动脉信噪比、对比度噪声比、描绘长度和血管清晰度显著增加。两次20 mL造影剂注射的成像方法在两次屏气中覆盖左和右冠状动脉，是一种有前途的冠状动脉成像方法。
A volume-targeted contrast agent-enhanced breath-hold coronary magnetic resonance angiographic technique was optimized and evaluated in 16 volunteers. Substantial increases in coronary signal-to-noise ratio, contrast-to-noise ratio, lengths of depiction, and vessel sharpness were observed on enhanced images. The imaging approach with two 20-mL injections of contrast agent covers the left and right coronary arteries in two breath holds and is a promising method for coronary imaging.
