Scan Comments: Scan ranges are limited to a specific area of interest to avoid unnecessary patient dose. Be sure to include entire renal vasculature if multiple arteries exist.  All scans are performed using the ALARA principle.

 

Technical Parameters

Time (Rotation)

0.5 sec

Average Acquisition Time

10-12 sec

Collimation

64 x 0.6mm

Pitch Value

Scan Direction

craniocaudal

Comments: The Effective mAs is adjusted based on a patient’s body habitus.  CareDose can be used to maintain image quality while lowering patient dose.  In addition, the dose can be lowered on noncontrast and delayed imaging to avoid unnecessary patient dose.
