Summary of 3D analysis methods

A1	Semi-automated volumetric method without manual correction
A2	Semi-automated volumetric method with manual correction of end-diastolic and end-systolic contours before processing the 3D dataset
A3	Semi-automated volumetric method with manual correction in all frames after processing the 3D dataset
B	Simpson's biplane method of discs on optimised orthogonal 2D planes of a 3D dataset
C	3D method of discs technique using short-axis slices

2D, two-dimensional; 3D, three-dimensional.
