  1. Assessed errors in myocardial tissue are comparable between native and post-contrast mapping from MOLLI and ShMOLLI, independently from respective T1 times. Blood T1 error exhibits significant dependence on respectively measured T1 time. Data is expressed mean percental deviation ± SD from T1 time measured with SASHA. p < 0.05 is considered statistically significant
