The Transaxial Orientation Is Superior to Both the Short Axis and Horizontal Long Axis Orientations for Determining Right Ventricular Volume and Ejection Fraction Using Simpson's Method with Cardiac Magnetic Resonance

<table>Multiplanar ED and ES data were combined to create a 3D representation of the RV that was then used to generate RV volume measurements using the PSSS method. (a)–(c) Representative sequential screen-saver images obtained during the contouring of the PSSS model. Endocardial contours of the RV free wall (purple lines) and septum (aqua lines) and anatomical landmarks such as the tricuspid valve (orange dots) and pulmonary valve (dark red dots) annuli were delineated on gray-scale images, eventually generating a 3D wire frame model of the RV. (d) This was subsequently reconstructed as a 3D triangulated mesh.</table>
