Radiologic images are vast three-dimensional data sets in which each voxel of the
underlying volume represents distinct physical measurements of a tissue-dependent …

Background: Atherosclerotic plaques are the major cause of coronary artery disease (CAD).
Currently, computed tomography (CT) is the most commonly applied imaging technique in …

We evaluated the accuracy of coronary artery calcium (CAC) scoring on a dual-source
photon-counting detector CT (PCD-CT). An anthropomorphic chest phantom underwent …

Coronary computed tomography (CT) allows for the acquisition of thin slices of the heart and
coronary arteries, which can be used to detect and quantify coronary artery calcium (CAC), a …

Exposure to ionising radiation is an important healthcare concern, primarily due to the
potential increased lifetime risk of malignancy. This is important for patients and staff who …

Background Filtered back projection (FBP) and adaptive statistical iterative reconstruction
(ASIR) are ubiquitously applied in the reconstruction of coronary CT angiography (CCTA) …

Background Volumetric and radiomic analysis of atherosclerotic plaques on coronary CT
angiography have been shown to predict high-risk plaque morphology and to predict patient …

Non-linear iterative reconstruction (IR) algorithms have been increasingly incorporated into
clinical cardiac CT protocols at institutions around the world. Multiple IR algorithms are …

Background: On the basis of the hypothesis that virtual noniodine (VNI)-based coronary
artery calcium scoring (CACS) is feasible at reduced radiation doses, this study assesses …

Purpose To determine the effect of model-based iterative reconstruction (IR) on coronary
calcium quantification using different submillisievert CT acquisition protocols. Methods …
