OBJECTIVES To identify an accurate and reproducible method to define myocardial infarct (MI) size, we conducted a study in a closed-chest canine model of acute myocardial infarction, in which MI size was measured using different thresholding techniques and by imaging at different delay times after contrast administration. BACKGROUND The MI size by(More)
A 59-year-old asymptomatic man, who had undergone cardiac valve surgery 40 years earlier, demonstrated a paracardiac mass on routine chest x-ray (Figure 1). Subsequently , a chest computed tomography scan was performed, which showed a 14.0ϫ9.5 cm heterogeneous lesion, with lobulated contours, along the inferior aspect of the left and right ventricles(More)
Coronary computed tomography angiography (coronary CTA) is a powerful non-invasive imaging method to evaluate coronary artery disease. Nowadays, coronary CTA estimated effective radiation dose can be dramatically reduced using state-of-the-art scanners, such as 320-row detector CT (320-CT), without changing coronary CTA diagnostic accuracy. To optimize and(More)
