Representative images of serial T2-TSE and T2-GraSE mapping. Representative T2-mapping images for all time-points from the same pig subjected to 40 min I/R and sacrificed at day 7 after reperfusion. a T2-TSE images. b T2-GraSE images. All T2 maps were scaled between 30 and 120 ms. All sequences were acquired with black-blood preparation prepulse. For better visualization, generated T2 maps were masked to remove background signal. The masking was defined in the first echo image to improve the contrast between the cardiac muscle and the cavity. R: Reperfusion
