This study presents a new approach to 2D TSE imaging using annular spiral rings with a retraced in/out trajectory, dubbed “SPRING-RIO TSE”, for fast T2-weighted brain imaging. Annular rings with retraced in/out segments offer benefits for reducing T2 decay induced artifacts and self-correction of moderate off-resonance effects. Phantom and human results show that high-quality T2-weighted images can be acquired with higher scan efficiency and reduced SAR, when compared with Cartesian TSE imaging.
