Calcified plaque has a major effect on increasing plaque volume which can increase the risk of Coronary Artery Disease (CAD). The use of Filtered Back Projection (FBP) on CT-scans still has flaws in terms of image quality that can result in errors in the calculation of plaque volume. Intelli IP Advanced is hitachi CT-scan’s Iterative Reconstruction (IR) type and can improve image quality compared to FBP. The purpose of this study is to find out the comparison of calcified plaque volume in coronary arteries using FBP and Intelli IP Advanced. This study used 38 samples of coronary artery blood vessels that had calcified plaque and reconstructed using the reconstruction of FBP and Intelli IP Advanced algorithms (Levels 1-3). Plaque calculation is done automatically using aquarius intuition edition application on CT-scan Hitachi SCENARIA 128 Slice. The results in this study found significant differences (p < 0.05) in calcified plaque volume results with the use of FBP and Intelli IP Advanced algorithm reconstruction (Levels 1-3). However, significant differences are found only in algorithm reconstruction pairs (Intelli IP Advanced Level 1 and Level 3) that have a p < 0.05. The conclusion is that IR affects the volume value of calcified plaque.
