Quantification of Coronary Plaque by 64-slice Computed Tomography: A Comparison with Quantitative Intracoronary Ultrasound

Abstract

Quantification of coronary plaque within selected proximal or middle coronary segments without image blurring and heavy calcification with 64-slice CT was moderately accurate with respect to intravascular ultrasound and demonstrated good reproducibility. Further improvement in CT resolution is required for more reliable measurement of coronary plaques using quantification software.
