  1. eCNR Estimated contrast-to-noise ratio, eSNR Estimated signal to noise ratio
  2. * Indicates significant differences with high-resolution WH-bSSFP technique (p < 0.05) as assessed by Friedman’s test with post-hoc testing using the Nemenyi test (Qualitative scoring)
  3. Indicates significant differences with low-resolution WH-bSSFP technique (p < 0.05) as assessed by Friedman’s test with post-hoc testing using the Nemenyi test (Qualitative scoring)
  4. ** Indicates significant differences with high-resolution WH-bSSFP technique (p < 0.05) ANOVA with post hoc testing using Holm correction (Quantitative scoring)
  5. †† Indicates significant differences with low-resolution WH-bSSFP technique (p < 0.05) ANOVA with post hoc testing using Holm correction (Qualitative scoring)
