Abstract:
Although coronary computed tomography angiography (CCTA) offers a valuable alternative for characterizing nonclacified coronary plaques, its value in evaluating noncalcified coronary plaques after an acute cardiac event (ACE) remains uncertain. We investigated the prevalence of ACE and the characteristics of clearly discernible noncalcified coronary plaques using dual-source CCTA. Forty patients with noncalcified coronary plaques demonstrated by dual-source CCTA were studied for 7 to 12 months. The prevalence of ACE with a diameter of the stenotic coronary vessel of more or equal to 50% and of less than 50% of the lumen of the stenotic coronary were grouped and compared. The noncalcified plaque was analyzed. Quantitative CCTA revealed 29 patients were with ≥50% of diameter stenosis (DS) and 9 of them had ACE; 11 patients were with

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
