Summary: The goal of this research is to validate novel non-invasive Magnetic resonance imaging (MRI) biomarkers to detect Gastroesophageal varices (GEV) in patients with cirrhosis, including fractional flow change in the portal vein and elevated azygos flow. End-stage liver disease (cirrhosis) is characterized by advanced fibrosis, liver failure, and portal hypertension. There are many causes of cirrhosis...

Summary: The purpose of this single-center, prospective, evaluator-blinded study is to establish and optimize the imaging protocol for ferumoxytol-enhanced magnetic resonance venography (Fe-MRV) in patients with venous system diseases. Current gadolinium-based contrast agents used in MRI have limitations, including short circulation half-lives and potential risks for patients with renal impairment. Ferumox...

Summary: This phase III trial is evaluating whether a combination of three advanced magnetic resonance imaging (MRI) techniques, including chemical exchange saturation transfer (CEST) MRI, diffusion-relaxation correlation spectrum imaging (DR-CSI), and ferumoxytol-enhanced magnetic resonance imaging (Fe-MRI) are effective as non-invasive methods for assessing the cells and proteins that surround and intera...
