Tri-phasic CT: Tri-phasic ct scans are used to evaluate the structure, the blood vessels and the nature of the organs. The three phases are: 1) before the intravenous contrast is given; 2) the arterial phase, when the dye is given rapidly as an injection, the effect is that it goes to the heart as a bolus and then to the aorta as a bolus, like an arteriogram; 3) the venous phase or equilibration phase.
