Volume acquisition and structural view of left atrium (LA) and left atrial appendage (LAA) obtained by using the three-dimensional multi-planar (axial, coronal and sagittal) reconstructions from multi-detector cardiac computer tomography. Determination of LA and LAA volume measures using three-dimension volume threshold-based method highlighted by the green zones. The top right images demonstrate the three-dimensional view of the LA, LAA and pulmonary veins
