磁化准备的T-2加权序列(T-2Prep)用于抑制肌肉和静脉结构。当与脂质抑制相结合时，这项技术可以改善冠状动脉的可视化。T-2 Prep被设计成在存在流动以及B-0和B-1不均质性的情况下具有健壮性，并且可以与几乎任何成像技术相结合。这里，它是用单层螺旋采集和多层螺旋方法实现的，多层螺旋方法在单个屏气间隔内采集多达15个切片。
A magnetization-prepared, T-2-weighted sequence (T-2 Prep) is used to suppress muscle and venous structures. When combined with lipid suppression, this technique improves the visualization of the coronary arteries. T-2 Prep was designed to be robust in the presence of flow as well as B-0 and B-1 inhomogeneities and may be combined with virtually any imaging technique. Here, it is implemented with both a single-slice spiral acquisition and a multi-slice spiral method that acquires up to 15 slices in a single breath-holding interval.
