Status Recruiting

Clinical Trial Summary

How to construct a novel, non-invasive, accurate, and convenient method to achieve prediction of hepatic venous pressure gradient (HVPG) is an important general problem in the management of portal hypertension in cirrhosis. We plan to investigate the ability of three demensional-magnetic resonance elastography (3D-MRE) to establish a risk stratification system and perform tailored management for portal hypertension in cirrhosis.

Clinical Trial Description

China suffers the heaviest burden of liver disease in the world. The number of chronic liver disease is more than 400 million. Either viral-related hepatitis, alcoholic hepatitis, or metabolic-related fatty hepatitis, etc. may progress to cirrhosis, which greatly threatens public health. Portal hypertension is a critical risk factor that correlates with clinical prognosis of patients with cirrhosis. According to the Consensus on clinical application of hepatic venous pressure gradient in China (2018), hepatic venous pressure gradient (HVPG) greater than 10,12,16,20 mmHg correspondingly predicts different outcomes of patients with cirrhosis portal hypertension. It is of great significance to establish a risk stratification system and perform tailored management for portal hypertension in cirrhosis. As a universal gold standard for diagnosing and monitoring portal hypertension, HVPG remains limitation for clinical application due to its invasiveness. How to construct a novel, non-invasive, accurate, and convenient method to achieve prediction of HVPG is an important general problem in the management of portal hypertension in cirrhosis. Multiparametric three-dimensional (3D) MR elastography allows for basic viscoelastic modeling of tissue, partitioning the complex shear modulus into elastic components (eg, storage modulus) and viscous components (eg, loss modulus and damping ratio [DR]). However, these mechanical properties of tissue measured with use of 3D MR elastography have yet to be investigated in cirrhosis to identify specific hepatic pathophysiologic interrelations. We hypothesize that these mechanical properties might be valid presumptive surrogates of cirrhosis and portal hypertension, perhaps capable of supplanting liver biopsy or other invasive diagnostic interventions. This project aims to investigate the ability of three demensional-magnetic resonance elastography (3D-MRE) to establish a risk stratification system and perform tailored management for portal hypertension in cirrhosis. ;
