Improving Cardiovascular Diagnosis in Computed Tomography Imaging with the Use of Artificial Intelligence
摘要
The application of artificial intelligence (AI) in cardiac computed tomography (CT) imaging represents a significant advancement in the management of coronary artery disease (CAD). AI enhances image quality, accelerates image analysis, and assists in identifying myocardial ischemia and hemodynamically significant stenosis. Convolutional neural networks (CNNs) have been employed to mitigate image noise in low-dose non-contrast cardiac CT scans, facilitating accurate coronary artery calcium (CAC) scoring. Additionally, CNN-based denoising algorithms applied to coronary computed tomography angiography (CCTA) improve CAD detection at reduced radiation doses. Furthermore, AI algorithms are applied for automatic segmentation of cardiac structures, essential for precise stenosis evaluation and coronary plaque characterization. Advanced AI methodologies, including deep learning and radiomics, enhance the assessment of plaque morphology and myocardial ischemia, with emerging applications in CT-derived fractional flow reserve (CTFFR), showing increased diagnostic accuracy. AI’s role in detecting pulmonary embolism (PE) further exemplifies its diagnostic potential, with AI algorithms demonstrating high sensitivity and specificity. The integration of AI in cardiac CT imaging is poised to optimize diagnostic workflows, enhance clinical decision-making, and improve patient outcomes.
