From: A practical biphasic contrast media injection protocol strongly enhances the aorta and pulmonary artery simultaneously using a single CT angiography scan

Fig. 2

Black: high density of contrast medium. White: low density of contrast medium. Time point 1 is before contrast medium injections; therefore, all the vascular structures are white. Time point 2 is about the midway of the two contrast injection phases and the first slowly injected contrast media, shown in gray color, arrive the pulmonary artery and at the same time, the second fast injected contrast media, shown in black color, arrive the superior vena cava. There is very low contrast media in the aorta at this time point. Time point 3 is the start point of the diagnostic scan. At this time point, the first slowly injected contrast media, shown in gray color, arrive the aorta and at the same time, the second fast injected contrast media, shown in black color, arrive the pulmonary artery
