  2. a Bland Altman analysis against the high-resolution WH-bSSFP data. Bias is the mean of the paired difference with the high-resolution WH-bSSFP. Limits of agreements are calculated as bias ± 1.96xSD
  3. *Indicates significant differences with standard high-resolution WH-bSSFP technique as assessed by ANOVA with post hoc testing using Holm correction (p < 0.05)
  4. Indicates significant differences with low-resolution WH-bSSFP technique as assessed by ANOVA with post hoc testing using Holm correction (p < 0.05)
