Figure 1 Base, Middle, And Apical Short-Axis CMR Slices Divided Into 8 Equidistant Radial Sectors
(Lower right panel) Schematic representation of the 3 concentric left ventricle short-axis slices segmented radially on a polar map. The plus (+) sign in blue in the cardiac magnetic resonance (CMR) images represents the anterior insertion of the right ventricle. The segments were assigned based on anatomic location of left anterior descending (base 1, 2, 8; middle 9, 10, 16; apical 17, 18, 24), diagonal branches (middle 9, 10; apical 17, 18), circumflex (base 3, 4; middle 11, 12; apical 19, 20), obtuse marginal branches (middle 11, 12; apical 19, 20), right coronary (base 5, 6, 7; middle 13, 14, 15; apical 21, 22, 23), posterior descending (apical 21, 22, 23), and posterior lateral (apical 20,21) arteries.
