Reproducibility of quantitative plaque measurement in advanced coronary artery disease.

ABSTRACT:

Background

The ability to characterize and to quantify the extent of coronary artery disease has the potential to improve the prognostic capability of coronary computed tomography angiography. Although reproducible techniques have been described in those with mild coronary disease, this has yet to be assessed in patients with advanced disease.

Methods

Twenty patients with known multivessel disease underwent repeated computed tomography coronary angiography, 2 weeks apart. Coronary artery segments were analysed using semi-automated software by two trained observers to determine intraobserver, interobserver and interscan reproducibility.

Results

Overall, 149 coronary arterial segments were analysed. There was excellent intraobserver and interobserver agreement for all p
