ABSTRACT
Objective：To detect the clinical applicative value of multi－slice spiral CT portal venography in displaying portacaval collateral vessels in patients of liver cirrhosis with portal hypertension.
Methods：92 patients of liver cirrhosis with portal hypertension underwent endoscopy and 8－detector row CT portal venography which need image postprocessing techniques to show the portacaval collateral vessels. It was studied that the degree of concordance between endoscopy and 8－detector row CT portal venography.
Results：Excellent image quality of portacaval collateral vessels with CTPV was obtained in all patients. The diameter of portal vein and left gastric vein was also obtained in this study. There was a good degree of concordance between CTPV and endoscopy in revealing esophageal varices（Kappa＝0.502）and gastric fundic varices（Kappa＝0.478）. |
