Enhanced Cardiac CTA Segmental Atherosclerosis Detection With Artificial Intelligence Quantitative Computed Tomography (AIQCT) Analysis Vs Conventional Reader Interpretation
Introduction: Number of coronary segments with atherosclerosis has been established as a plaque burden risk marker in cardiac coronary CT angiography (CCTA). Artificial intelligence quantitative computed tomography (AIQCT, Cleerly Inc, Denver, CO) analysis automatically detects coronary atherosclerosis and may identify higher segmental and artery atherosclerosis prevalence than conventional visual reader interpretation. We aimed to evaluate whether and to what degree this occurs in a high volume single center clinical setting. (Source: Journal of Cardiovascular Computed Tomography)

Assessment Of Coronary Plaque Composition And Distribution On Ccta: Implications For Disparities In Clinical Presentation And Outcomes
Introduction: Determination of coronary plaque composition and distribution on CCTA is important for the appropriate evaluation and management of cardiovascular patients. While coronary artery calcium (CAC) scores have traditionally been used to assess the risk of future cardiovascular events, relying solely on calcified plaques does not provide a complete picture of risk and potential outcomes. This is because CAC scores only account for calcified plaques and do not measure non-calcified plaques. (Source: Journal of Cardiovascular Computed Tomography)

The Prevalence Of Atherosclerosis Identified On Coronary CT Angiography Among Patients With Chronic Kidney Disease And Its Impact On Statin Utilization
Introduction: Chronic kidney disease (CKD) is associated with increased atherosclerotic cardiovascular disease (ASCVD) risk and high plaque burden. Standard risk calculators underestimate ASCVD risk and guideline-based preventive medications are underutilized. Among patients with non-dialysis-dependent CKD, ASCVD prevention guidelines recommend statin and/or ezetimibe in most or all patients with stage 3 CKD or greater. Our objective was to determine the prevalence of atherosclerosis among patients with CKD stage 3-4 referred for coronary CT angiography (CCTA), and the use of statin/ezetimibe before and after CCTA among pa...

Primary Results Of The REVEALPLAQUE Study: A Prospective Quantitative Assessment Of AI-based CCTA Plaque Volume Compared With IVUS
Introduction: Coronary plaque burden and composition are strong prognostic markers in patients with coronary artery disease, but direct validation of noninvasive plaque measures compared to invasive imaging reference standards employing convenient automated mechanisms are limited. The purpose of this study was to compare an AI-enabled quantitative plaque analysis (AI-PA) derived from coronary computed tomography angiography (CCTA) to intravascular ultrasound (IVUS).

Effect Of Virtual Monoenergetic Reconstructions On Coronary Plaque Volumes Using Photon-counting Computed Tomography
Introduction: Photon-counting CT (PCCT) provides virtual monoenergetic images (VMIs) which may allow for more precise assessment of coronary plaques. We aimed to assess how plaque component volumes change on different VMIs. (Source: Journal of Cardiovascular Computed Tomography)

Diagnostic Accuracy Of Photon-Counting CT For Detecting Obstructive Coronary Artery Disease
Introduction: Photon counting coronary CT angiography (PCCT) opened a new horizon in coronary stenosis assessment with high spatial resolution and utilizing spectral information. We aimed to evaluate the diagnostic accuracy of PCCT in patients with obstructive coronary stenosis regarding invasive coronary angiography (ICA) as a reference standard. In a sub-analysis, we also assessed the diagnostic accuracy of the ultra-high resolution (UHR) PCCT images. (Source: Journal of Cardiovascular Computed Tomography)

Using Coronary Computed Tomography Angiography And Coronary Artery Calcium Score To Assess Correlation Between Non-alcoholic Fatty Liver Disease And Coronary Artery Disease
Introduction: Studies have demonstrated an association between Non-Alcoholic Fatty Liver Disease (NAFLD)/Non-Alcoholic Steatohepatitis (NASH) and atherosclerosis. Whether NAFLD is an independent risk factor for coronary artery disease and other cardiovascular events based on liver biopsy (LBx) findings remains controversial.

Investigating Low Endothelial Shear Stress And Microcalcification Activity In Patients With Acute Coronary Syndrome
Introduction: Shear stress modulates endothelial function and low shear stress is linked with coronary plaque progression. Microcalcification activity also promotes plaque development and risk, with microcalcification activity detectable non-invasively with sodium flouride (NaF) PET. Our hypothesis is that low shear stress will be associated with microcalcification activity in atherosclerotic coronary arteries. (Source: Journal of Cardiovascular Computed Tomography)
