Abstract
Fully automated segmentation of left atrium and pulmonary veins in late gadolinium enhanced MRI
Highlights
Late gadolinium enhanced (LGE) MRI enables scar assessment in the left atrial (LA) wall, providing valuable information for treatment planning and image based procedure guidance in patient with atrial fibrillation (AF)
A contrast-enhanced MRA sequence was used for assessment of the anatomy followed by LGE MRI for atrial scar assessment
Three-dimensional region-growing and active contour refinement was applied to the multiplied volume for refined segmentation of the LA endocardial wall and further identification of pulmonary veins (PV) (Figure 1d)
