Highly accelerated real-time T 2 -weighted imaging with through-time radial GRAPPA and low-latency GPU reconstruction

Background T2-weighted cardiac images are commonly used for edema detection [1-4]. However, neither black-blood TSE nor cine images can offer real-time edema monitoring, and are therefore not suitable for the guidance of cardiac ablation procedures. We proposed a radial T2weighted interrupted balanced SSFP (rT2W-iSSFP), a real-time high temporal resolution sequence targeted at monitoring edema.
