  1. Extent refers to the percentage of segments affected.
  2. Transmurality was scored as 1 = 1–25%, 2 = 26–50%, 3 = 51–75% and 4 = 76–100%. Duration refers to the number of frames for which the defect was visible.
  3. The p values relate to the difference between the scores with st-GrE and ktBLAST-SSFP in both patients and volunteers.
