用于MR血管造影术的传统团注标记技术的一个限制是由一个标记标记的少量血液，导致下游血管的有限填充。我们描述了一种多团技术，使用刺激回波（STE）成像冠状动脉流量。给出一系列射频（RF）对，其中每对在标记区域处具有选择性，从而标记连续体积的血液，并且给出最终非选择性脉冲以“读出”所有标记的自旋。以这种方式，标记血液的多个推注一次成像。
One limitation of traditional bolus tagging techniques for MR angiography is the small amount of blood labeled by one tagging, resulting in a limited filling of the downstream vessels. We describe a multiple bolus technique using stimulated echoes (STE) for imaging coronary flow. A series of radiofrequency (RF) pairs are given with each pair selective at the region of tagging, thus tagging consecutive volumes of blood, and a final nonselective pulse is given to “read out” all of the tagged spins. In this way, multiple boluses of tagged blood are imaged at one time.
