About this study
Official title: MR-based Models for Noninvasive Detection of Clinically Significant Portal Hypertension in Cirrhosis (CHESS1802)
Clinically significant portal hypertension (CSPH) is associated with an incremental risk of esophageal varices and overt clinical decompensations in cirrhosis. However, hepatic venous pressure gradient (HVPG) measurement, the gold standard for defining CSPH (HVPG≥ 10mmHg) is invasive and therefore not suitable for routine clinical practice.
This is a multi-center diagnostic trial conducted at high-volume liver centres designed to determine the accuracy of MR-based models (investigational technology) for noninvasive detection of a CSPH in patients with cirrhosis. Transjugular HVPG measurement by means of catheterization of a hepatic vein with a balloon catheter is the gold-standard method to assess the presence of CSPH.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Clinically significant portal hypertension (CSPH) is associated with an incremental risk of esophageal varices and overt clinical decompensations in cirrhosis. However, hepatic venous pressure gradient (HVPG) measurement, the gold standard for defining CSPH (HVPG≥ 10mmHg) is invasive and therefore not suitable for routine clinical practice.
This is a multi-center diagnostic trial conducted at high-volume liver centres designed to determine the accuracy of MR-based models (investigational technology) for noninvasive detection of a CSPH in patients with cirrhosis. Transjugular HVPG measurement by means of catheterization of a hepatic vein with a balloon catheter is the gold-standard method to assess the presence of CSPH.
