:#Normal-radiation-dose with split bolus IV contrast, 7.5 minutes and 90 seconds before image acquisition.
*In patients over 40 years, or younger if suspicion of cancer is high:
:#Low-radiation-dose of whole abdomen, without IV contrast
:#Normal-radiation-dose of whole abdomen 20 seconds after [[bolus tracking]], for visualization of renal cortex.
