Value of [68Ga]Ga-PSMA-11 PET/MRI in the Assessment of Liver Cirrhosis
Trial Parameters
Brief Summary
A total of fifty-five (55) patients with liver cirrhosis will be enrolled in this study to produce and validate dedicated Ga-PSMA-PET/MRI acquisition protocols. The specific hypotheses include: * Ga-PSMA PET/MRI may allow robust and reproducible noninvasive in vivo quantitation of hepatic macro and microhemodynamics in cirrhotic patients * Dedicated simultaneously acquired DWI sequences might quantitate liver fibrosis and improve hemodynamic quantitation. * Ga-PSMA PET/MRI may allow noninvasive and reproducible quantitation of portal venous hypertension and predict its evolution, as well as response to treatments * Ga-PSMA PET/MRI may improve noninvasive and reproducible qualitative and quantitative assessment of liver function, structure, nodules and predict evolution of cirrhosis
