With improvement of spiral CT scanning and 3-dimensional 3-D angiographic reconstructive techniques, portal vasculature may be visualized more accurately. In a prospective study that compared the technical success rate and accuracy of shear-wave elastography SWE and TE for the detection of clinically significant portal hypertension PH in 79 patients with advanced cirrhosis who underwent SWE and TE at the time of HVPG measurements, Elkrief et al reported that the evaluation of liver stiffness for clinically significant PH had a higher technical success rate and improved diagnostic value when obtained via SWE than by TE.

Source rise of portal pressure after sclerotherapy, but not band ligation, in acute variceal bleeding in cirrhosis. Limitations of ultrasonography include the fact that the reproducibility of data is problematic with that many variables, such as circadian rhythm, meals, medications, and the sympathetic nervous system, affect the portal hemodynamics. Liver-screen scanning is described for historical interest only, because this technique has been superseded by ultrasonography and CT varices. A portal balloon catheter is introduced into the femoral or internal jugular vein and advanced under fluoroscopy into a branch of the hepatic vein. Further studies hypertension evaluation being conducted to validate this.
