Design outcomes

Primary

Measure	Time frame
The amount of Hounsfield Units (HU) measured in the aorta at 30 positions from the celiac trunk to the iliac arteries in both groups.	—

Secondary

Measure	Time frame
- The contrast enhancement curve over time in the multiphasic injection with bolus reduction protocol. - The uniformity of the attenuation values of both protocols. - The volume of contrast medium that is used. - The clinical usefulness of the scans determined by 3 radiologists and scored at a scale from 1 to 3.	—
