CT Approach to Hepatic Vascular and Segmental Anatomy in Abdominal Survey and Liver Survey
|
|
|
|

Abstract
|
|
|
The goal of hepatic imaging technique should be to provide surgeon with information needed for management decision. Visualization of the hepatic veins and the other landmarks of hepatic segmental anatomy is the cornerstone of this process. CT
technique
now utilized in this hospital provided these information in 67% of abdominal survey and liver survey. In hepatocellular carcinoma, maor problems associated with the visualization of major vessels were portal vein thrombosis and large tumr, in
wich
cases
major vessels couldn't be visualized.
Dye amount, the method of dye injection, scan time and interscan delay time should be standardized to improve the rate of major vessel enhancement.
CT hepatic arteriography and CT arterial portography may render better visualization of major and segmental vessels, and may detect smaller hepatocellular carcinoma than CT.
