Interventions

30 Patients are randomly assigned to either standard or multiphasic protocol. 15 Patients undergo standard protocol, 15 patients undergo the multiphasic protocol. The multiphasic protocol injects co

the total volume of contrast medium is injected is less (89 ml instead of 100 ml). For research purposes low-dose scans will be made for an additional 20 seconds after the diagnostic scan is finishe

Design outcomes

Primary

Measure	Time frame
- The amount of 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 aorta in the multiphasic 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 blinded radiologists (of whom one is not connected to the Jeroen Bosch Ziekenhuis) and scored at a scale from 1 to 3.	—
