Basic Treatment Planning

Whole heart and pericardium

• Feng et al:  Superiorly: Start just inferior to the left

pulmonary artery, include the great vessels in a rounded contour  Inferiorly: Heart blends with the diaphragm. Cardiac vessels are in the fatty tissue within the pericardium, so should be included in the contours, even if there is no heart muscle visible.  If contrast is present, the SVC can be contoured separately from the whole heart. If not possible, include in whole heart contour
