Optimized Single-Shot EPI Sequence for Abdominal T2 Quantification: Comparison with CPMG Based Technique

Conventional CPMG-based T2 quantitative approaches are often based on prolonged scan and complicated signal modeling, with multiple confounders that affects the T2 accuracy. In this work, we explore an alternative T2 quantitative strategy utilizing the Single-Shot EPI (SS-EPI) sequence. Phantom and in-vivo abdominal imaging results shows that despite the inferior spatial resolution, the SS-EPI could provide descent image quality and reliable T2 maps from a faster scan. Common confounders in the CPMG based approach seems not affecting the T2 values from the SS-EPI. The SS-EPI is an attractive alternative approach for T2 quantification for the abdomen and beyond.
