Radial TSE techniques have been proposed for abdominal T2-weighted (T2w) imaging and T2 mapping. Slice efficiency of breath-held RADTSE is limited by the specific absorption rate (SAR). We present a reduced SAR variable refocusing flip angle RADTSE (RADTSE-VFA) technique designed for efficient slice coverage and improved T2 estimation. The flip angles are designed to (1) minimize T2 estimation error, (2) improve lesion-liver relative contrast, and (3) minimize SAR. RADTSE-VFA generated T2w images with comparable contrast as constant flip angle RADTSE while resulting in a 60% increase in slice coverage at a 1.5x reduction in SAR.
