Table 4 Manual inter-observer agreement (\(\mathrm{n}=37\)) of left atrial (LA) derived parameters for end-diastolic volume (EDV), end-systolic volume (ESV), ejection fraction (EF) and global longitudinal strain (GLS)

From: Automated left atrial time-resolved segmentation in MRI long-axis cine images using active contours
