Figure 2
The effect of partial volume on A) average myocardial T1 and B) average segmental pixel variability. Notes: Myocardial ROI thickness is calculated as distance between endo- and epi-cardial contours. Filled large symbols represent the T1 derived from myocardial contours drawn manually by the operator (original) compared to systematic erosion or dilatation in 1-pixel increments. P values refer to comparisons between subsequent inflation/erosion steps.
