Portal venous phase | Radiology Reference Article ...

17-11-2021 · The portal venous phase, also known as the late portal phase or hepatic phase, is a contrast-enhanced CT or MRI series that has the following characteristics: liver parenchyma is at its peak enhancement with a density 110 HU (an increase of at least 50 HU from the unenhanced baseline) 1,2 portal vein and hepatic veins are completely enhanced

Portal Vein Stenting for Delayed Jejunal Varix Bleeding ...

Objective: The study aimed to describe portal stenting for postoperative portal occlusion with delayed (≥ 3 months) variceal bleeding in the afferent jejunal loop. Materials and methods: Eleven consecutive patients (age range, 2-79 years; eight men and three women) who underwent portal stenting between April 2009 and December 2015 were included in the study.

The Radiology Assistant : CT contrast injection and protocols

01-06-2014 · For Late portal venous phase imaging it is different. Here you don't want to be too early, because you want to load the liver with contrast and it takes time for contrast to get from the portal vein into the liver parenchyma. Besides you have more time, because the delayed or equilibrium phase starts at about 3-4 minutes.

The Radiology Assistant : Characterisation of liver masses

15-07-2006 · The best moment to start scanning is at about 75 seconds, so this is a late portal venous phase, because enhancement of the portal vein already starts at 35 sec in the late arterial phase. This late portal venous phase is also called the hepatic phase because there already must be enhancement of the hepatic veins.

Delayed Imaging in Routine CT Examinations of the Abdomen ...

All patients underwent a routine contrast-enhanced CT examination that included two phases: an acquisition through the abdomen and pelvis 80 seconds after contrast administration (portal venous phase) and an additional acquisition from the dome of the liver to the bottom of the kidneys 3 minutes later (delayed phase).
