在15名接受冠状动脉磁共振（MR）血管造影的健康志愿者中，测量了有和无预充氧的屏气时间。评价预充氧对冠状动脉成像的影响。采用稳态进动序列三维磁共振真快速成像技术进行冠状动脉成像。所有受试者在预充氧后的舒适屏气时间均增加。这一额外的成像时间使得冠状动脉成像具有更高的空间分辨率。(C)RSNA，2003年。
In 15 healthy volunteers undergoing coronary magnetic resonance (MR) angiography, the breath-hold duration with and without preoxygenation was measured. The effect of preoxygenation on coronary artery imaging was also evaluated. A three-dimensional magnetization-prepared true fast imaging with steady-state precession sequence was employed for coronary MR angiography. All subjects showed an increase in comfortable breath-hold duration with preoxygenation. This extra imaging time allowed coronary artery imaging with increased spatial resolution. (C) RSNA, 2003.
