Molloi et al. (2001) studied Coronary artery disease (n=9). Video densitometry technique vs. Polymer cast of the coronary arterial tree was evaluated on Correlation between measured cast volume and video densitometric regional lumen volume (r=0.99). A video densitometry technique for quantifying coronary lumen volume showed excellent correlation with polymer cast measurements (r=0.99), demonstrating its feasibility for accurate in vivo assessment.
