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.

Fast and drink prep: You will be asked to fast for several hours beforehand. Then, you will probably be given some flavored contrast to drink, which is a type of dye to make the scans show more detail. You may also need to have an IV inserted to get IV contrast. The exact details will vary based on why the scan was ordered. The radiology department will give you exact instructions for your particular test.

Too long to list: Ct scan is a form of x-ray in which the radiation source & detectors rotate around the patient as she moves through the plane of the beam. As with all x-rays, it measures different density to the radiation, but the computer takes the raw data and reconstructs cross sectional images like slices of bread. While still limited to differences in density, it can resolve to a few millimeters.
