(a) Illustration of the Shepp-Logan phantom used for simulation. (b) T₂W-TSE and (c) r T₂W-iSSFP were simulated. Swine with acute injury was scanned by (d) breath-hold T₂W-TSE and (e) free-breathing r T₂W-iSSFP as well. The edema (the arrows in d) is depicted in both d and e. In both simulation and in-vivo imaging, T₂W-TSE was used as the reference of T₂-weighting. T_acq - acquisition time.
