Figure 1

Example of MRI analyses of the right ventricle (RV). Endocardial contours of the RV in end-diastolic phase (A) and end-systolic phase (B) are manually drawn on the short-axis view to assess volumes and RV systolic function. The papillary muscles, trabeculae carnae, trabecula septomarginalis (moderator band), and RV outflow tract are included in the ventricular volume. The RV outflow tract ends at the pulmonary valves (arrowheads). Furthermore, pulmonary artery flow curve is obtained. A phase contrast velocity map across the pulmonary valve (left) and a modulus image (right) are shown in one cardiac phase (C). RV inflow curve across the tricuspid valve was used to assess RV diastolic function. A phase contrast velocity map across the tricuspid valve (left) and a modulus image (right) are shown in one cardiac phase (D). E indicates early diastolic filling phase; A, atrial contraction.
