Figure 2

Showing matched short axis slices in systole and diastole in a patient with and without pulmonary hypertension. (1) A patient with pulmonary hypertension, image in diastole (a) the RV mass is less conspicuous than shown in systole (b), as a result the RV endocardial border is more easily appreciated in systole compared to diastole. This observation is mirrored in the patient without pulmonary hypertension (2), and likely explains the higher mean systolic RV mass and its higher reproducibility.
