Fig. 3A —Time–attenuation curves in control group and subgroups. Aorta = {diamondsuit}, pulmonary artery = {blacksquare}. Control curves show typical pulmonary artery enhancement pattern with early rising and subsequent plateau. Time–attenuation parameters, including maximal slope of pulmonary enhancement (MSPA), time to maximal slope of pulmonary enhancement (tMSPA), area between curves of pulmonary artery and aorta (ABC), and mean ratio of pulmonary artery and aortic enhancement (PA/AO), are illustrated.
