Summary
Delayed-enhancement magnetic resonance imaging is a powerful tool for detecting myocardial fibrosis and scarring in both the ventricles and atria. Recently there has been much interest in the quantification of DE-MRI for a variety of applications. The quantification of DE-MRI in the left atrium (LA) of patients with atrial fibrillation has been shown to be potentially useful for selecting suitable candidates for ablation therapy and the subsequent monitoring of this therapy. This quantification is particularly challenging due to the thin myocardium of the atrium and the difficulties in imaging these patients at sufficient resolution and signal-to-noise ratio. This challenge-workshop will make available 60 DE-MRI clinical data sets to challengers for segmentation of enhanced regions from patients with atrial fibrillation. 30 data sets will be from patients prior to ablation therapy for fibrosis segmentation and 30 will be at least 3-months post-ablation therapy for ablation-related scar segmentation. Data provided will include the DE-MRI and a segmentation of LA endocardium from an anatomical MRI. Ground truth will be established by using manual segmentations from clinical experts.
