Comparison with threshold levels proposed by other studies on 3 months post-ablation data-sets. Comparison of enhancement segmentation techniques on a 3 months post-ablation LGE CMR data-set of a long-standing persistent AF patient. Left Short-axis slices of the original data-sets zoomed-in on the left atrium. Middle The enhancement segmentation results of the algorithm proposed in this study. Right The enhancement segmentation results of the algorithm proposed in [18]. All enhanced tissue segmentation results appear highlighted in red and have been super-imposed on the LGE CMR slices. The threshold level proposed in another study (T _POST  = 3 for study cited in [18]) led to gross underestimation of the enhancement. A anterior, P posterior, L left, R right
