title: Correlation of scintigraphy and angiography for ventricular volume determinations using realistic cardiac phantoms: the unimportance of self-attenuation.
abstract: The volumes of the left ventricle (LV) and right ventricle (RV) were determined by scintigraphy, radiography, and weight, using hollow, morphologically accurate cardiac phantoms that ranged from 99-415 ml (RV) and 72-364 ml (LV). Self-attenuation within these simulated ventricles appeared negligible in view of the nearly linear correlation between scintigraphic and weight determined volumes. Scintigraphy compared favorably with radiography for estimating clinically encountered volumes of the RV and LV.
