MTC‐BOOST pulse sequence diagram. Magnetization transfer (MTC) in combination with an inversion pulse (IR) is used in the odd heartbeats to acquire a magnitude volume (MTC‐IR BOOST, a), whereas only magnetization transfer preparation (MTC‐BOOST) is performed in the even heartbeats (b). Data acquisition is performed using a 3D Cartesian trajectory with spiral‐like order, segmented over multiple heartbeats. For respiratory motion correction, low‐resolution 2D image‐based navigator (iNAV) is acquired in each heartbeat. A nonrigid motion correction is applied on each volume, which are then combined with a PSIR reconstruction to generate a co‐registered black‐blood volume (c).
