MOCO-MAP using a TWIRL trajectory

摘要

Cardiac delayed enhancement imaging is time-consuming and requires many breath holds of the patient. Additionally, the procedure demands for TI scouting to yield optimal contrast [1]. As an alternative, MOCO-MAP (Motion Corrected-Model-based Acceleration of Parameter mapping) provides an image reconstruction from a single FLASH acquisition [2]. Beyond that, it allows adjusting the TI dependent contrast in post-processing. So far, the k-space trajectories were limited to radial sampling patterns, which inefficiently cover the outer parts of the k-space [3]. Hence, the objective was to implement a more elaborate acquisition trajectory and to test the sequence in vivo.
