Proposed iT2Prep‐BOOST acquisition and reconstruction scheme. (a) 3D data acquisition is performed in an interleaved fashion, with a combined T2‐preparation and inversion recovery (T2Prep‐IR) preparation pulse used in odd heartbeats, and only fat saturation used in even heartbeats. The sequence integrates image navigators (iNAVs) for motion compensation and 100% respiratory scan efficiency. (b) Superior inferior (SI) motion estimated from the iNAVs is used to bin the data and produce respiratory‐resolved 3D bin images, which are then used to estimate 3D nonrigid motion. (c) Co‐registered motion‐corrected 3D images are obtained by incorporating nonrigid motion into the reconstruction and low‐rank patch‐based denoising, which are finally used to obtain the bright‐blood data for lumen visualization (odd heartbeats) and black‐blood data for vessel wall visualization (by direct subtraction of even and odd heartbeats).
