Table 2. Native, post-contrast T1 and corresponding ECV for the esixting data by MyoMapNet and MOLLI. MyoMapNet T1 were calculated by discarding T1-weighted images from the MOLLI sequence

  1. ECV Extracellular volume. Mean and standard deviation were calculated by averaging the corresponding results of each subject across all subjects
  2. §p-value < 0.05 when compared to MOLLI5(3)3 or MOLLI4(1)3(1)2
