Recently, there has been renewed interest in imaging at low field strengths. The increased T2* relaxation times at 0.55T and reduced chemical shift between fat and water requires the need for longer TEs for accurate fat fraction and R2* estimation, often resulting in longer acquisition times. In this work, we present a scan-efficient hybrid TSE-GRE technique for the simultaneous acquisition of T2- and T1-weighted images along with quantification of fat fraction and R2*. The use of a stack-of-stars trajectory allows SNR efficient free breathing imaging at 0.55T.
