Improving segmentation of calcified and non-calcified plaques on CCTA-CPR scans via masking of the artery wall [PDF]
SPIE 12465, Medical Imaging 2023: Computer-Aided Diagnosis, 2022 The presence of plaques in the coronary arteries is a major risk to the patients' life. In particular, non-calcified plaques pose a great challenge, as they are harder to detect and more likely to rupture than calcified plaques. While current deep learning techniques allow precise segmentation of real-life images, the performance in medical images is ...

Automated analysis of fibrous cap in intravascular optical coherence tomography images of coronary arteries [PDF]
arXiv, 2022 Thin-cap fibroatheroma (TCFA) and plaque rupture have been recognized as the most frequent risk factor for thrombosis and acute coronary syndrome. Intravascular optical coherence tomography (IVOCT) can identify TCFA and assess cap thickness, which provides an opportunity to assess plaque vulnerability.

Optical imaging techniques for vulnerable plaque detection
Translational Biophotonics, 2020 Vulnerable plaque rupture is the most important cause of myocardial infarction and acute coronary syndrome. Therefore, identifying vulnerable plaques is of prime importance, which will in turn aid in the development of treatments to stabilise them ...

Wall Shear Stress Analysis in Stenosed Carotid Arteries with Different Shapes of Plaque [PDF]
International Journal of Computer Applications, Volume 145, No.4,
July 2016, 2017 Atherosclerosis is a disease caused due to formation of plaque into the artery. Increase in plaque affects the wall shear stress. The present study is performed to calculate wall shear stress in different geometries of stenosed carotid artery. A 2D model of different geometries is generated using CFD for Non- Newtonian model.

The Impact of Coronary Artery Calcification on Long-Term Cardiovascular Outcomes
Journal of Interdisciplinary Medicine, 2021 Decades of research and experimental studies have investigated various strategies to prevent acute coronary events. However, significantly efficient preventive methods have not been developed and still remains a challenge to determine if a coronary ...

Imaging Vulnerable Plaque by Ultrasound
Journal of the American College of Cardiology, 2006 Diagnostic techniques to identify vulnerable plaques are rapidly evolving. Intravascular ultrasound (IVUS) has the ability to detect and localize plaque as well as quantitate plaque burden. Recent IVUS studies have suggested that patients presenting with acute coronary syndromes have an approximate 25% incidence of additional ruptured plaques in ...

Mechanisms of plaque vulnerability and rupture [PDF]
Journal of the American College of Cardiology, 2003 Rupture of atherosclerotic plaque has been identified as the proximate event in the majority of cases of acute ischemic syndromes. Plaque rupture exposes thrombogenic components of the plaque, activating the clotting cascade and promoting thrombus formation.
