Detector Collimation (mm)1
Slice Thickness (mm)1.25
Data Reconstruction Interval (mm)1
Table Speed (mm per rotation) / Pitch6/6
Oral Contrast750 cc of water
IV Contrast Volume and Type120-150 cc of Omnipaque 350
Injection Rate3 cc/sec
Scan Delay (sec)25-30/60
3D Technique UsedVolume rendering/MIP
This protocol is a dual phase study that focuses on creating a detailed vascular map. Volume rendering is best for the arterial and venous mapping, but MIP helps with the hepatic veins on the venous phase.
