T2prep Inversion Recovery (T2IR) is a magnetization preparation technique that combines two preparations: T2prep and Inversion Recovery, in order to provide both T1 and T2 contrasts. Subsequently, T2IR provides flow-insensitive global black-blood suppression suited for slow flow at the expense of SNR, being suitable for 3D volumetric black-blood imaging of vessel walls where slow blood flow is observed. In this study, we examined the performance of using a T2IR preparation in both FSE and SSFP sequences to image a large 3D coronal volume (20cm x 20cm x 5.2cm) at a submillimeter isotropic spatial resolution of 0.8mm.
