Right ventricular (RV) chamber quantification. For RV volume quantification, the endocardial (red) contours are delineated in diastole (a) and systole (b) in a stack of transaxial slices covering the whole RV (top). Alternatively, a stack of short axis slices can be used (c, d). Here, the yellow contours indicate the RV in diastole (c) and systole (d); the RV is contoured following the LV analysis (in c and d, red / green contours indicate endocardial / epicardial borders of the LV) and with reference to the LV
