Tracing ventricular borders. Diagram demonstrating the drawing of left and right ventricular endocardial contours in end-diastole. Images may be acquired in a ventricular short-axis orientation (A and B) or in an axial orientation (C and D). There is practice variation regarding whether to trace the papillary muscles and right ventricular trabeculations to exclude them from (A and C) versus include them in (B and D) the blood pool.
