2D spatially selective radiofrequency (RF) pulses can be used to constrain the location from which an MR signal is obtained. This may lead to more time-efficient data collection by reducing the field of view (FoV) or may improve image quality by suppressing artefacts from outside the area of interest. Meanwhile, T2-Preparation, or T2-Prep, is a magnetization preparation scheme used to improve blood/myocardium contrast. We propose incorporating a "pencil-beam" 2D RF pulse into a T2-Prep module, so as to produce a "2D T2-Prep" that combines T2-weighting with an intrinsic spatial selectivity.
A 2D T2-Prep shows promise to both reduce respiratory motion artefacts and decrease scan time, while preserving the T2-weighting of a conventional T2-Prep. It should thus be considered as a potential tool in accelerated cardiac imaging.
