CT Contrast Timing – Radiology Protocols

Portal Venous Phase: 35 seconds after HU trigger Final Phase: 120 seconds after HU trigger The arterial phase on these examples will be a little bit more delayed than the arterial phase on a true arterial based examination such as an aorta study where the scanner is trigger immediately upon reaching the target HU (i.e. no 18 second delay)

The Radiology Assistant : Characterisation of liver masses

15-07-2006 · In the arterial phase hypervascular tumors will enhance via the hepatic artery, when normal liver parenchyma does not yet enhances, because contrast is not yet in the portal venous system. These hypervascular tumors will be visible as hyperdense lesions in a relatively hypodense liver. However when the surrounding liver parenchyma starts to enhance in the …

CT Scan of the Liver and Enhancing Phases - RadTechOnDuty

27-03-2017 · Phases of Enhancement in Liver. Because the liver derives approximately 25% of its blood supply from the hepatic artery and the remaining 75% from the portal vein, there are several phases of enhancement after the intravenous administration of a bolus of contrast material. The first is the hepatic arterial phase typically occurring 15 to 25 ...
