Abstract

Purpose: The purpose of this study was to study the effect of iterative reconstruction (IR) software on
quantitative plaque measurements in coronary computed tomography angiography (CCTA).
Methods: Thirty patients with a three clinical risk factors for coronary artery disease (CAD) had one CCTA
performed. Images were reconstructed using FBP, 30% and 60% adaptive statistical IR (ASIR). Coronary
plaque analysis was performed as per patient and per vessel (LM, LAD, CX and RCA) measurements.
Lumen and vessel volumes and plaque burden measurements were based on automatic detected contours
in each reconstruction. Lumen and plaque intensity measurements and HU based plaque characterization
were based on corrected contours copied to each reconstruction
