Does a hemielliptical model accurately calculate right ventricular volume compared to direct measurement in human right ventricle casts?
Effect estimate: r = 0.99
A new hemielliptical model allows for accurate calculation of right ventricular volume from biplane radiographs, closely matching direct measurements.
Boak et al. (1977) studied Right ventricular volume measurement (n=7). Hemielliptical model for calculating right ventricular volume vs. Directly measured volume by water displacement was evaluated on Agreement between calculated volume and displacement volume (r = 0.99). A new hemielliptical model for calculating right ventricular volume from biplane radiographs showed close agreement with directly measured cast volumes (r = 0.99).
