- W2375965703 abstract "Objective To evaluate the effects of multislice CT detecting and quantify coronary artery calcium plaques with different reconstruction methods of retrospectively ECG-gated multislice CT, and to choose the optimal reconstruction method for coronary artery calcium. Methods Fifty-five patients underwent coronary artery calcium (CAC) studies with retrospectively ECG-gated multislice CT. Each patient's data was reconstructed with three different slice thickness (2, 3 and 5 mm) and increment overlapping by 50%. The volume score (VS), mass score (MS) and agatston score (AS) were measured and compared. Results The number to detect all calcium plaques were 234 and small calcium plaques were 185 in images with 2 mm slice thickness; Compared with 2 mm slice thickness images, the sensitivity to detect all calcium plaques and small calcium plaques were 84%, 62% and 83%, 54% in images with 3 mm, 5 mm slice thickness respectively. There was a smaller value in VS, MS and AS in 5 mm group than 2 mm and 3 mm group (P0.05), and 3 mm group than 2 mm group (P0.05). Conclusion Thinner slice imaging with overlapping reconstruction methods should be used in detecting and quantifying coronary artery calcium plaques. 2 mm images can detect more and smaller calcium plaques. It is essential to detect coronary artery calcium plaques and predict coronary events in clinical practice." @default.
