Table 3 Mean ± standard deviation of the subjective scores by two independent readers for different sequences and different criteria (i.e. LV scar detection, LV scar localization and papillary muscle scar detection) in the human dataset

From: Gray blood late gadolinium enhancement cardiovascular magnetic resonance for improved detection of myocardial scar

  1. aData (mean ± standard deviation) are computed over the datasets using the mean score of the two readers. Score values are: 1 = Challenging, 2 = Difficult, 3 = Moderate, 4 = Easy. GB gray blood, BB black blood, LGE late gadolinium enhancement
  2. bData represent the p-value of the post hoc pairwise Wilcoxon signed-rank test
