Evaluation of Multi-Organ Metabolism and Perfusion in NAFLD by Total Body Dynamic PET Scan on EXPLORER

Clinical Trial ID: NCT04165343


Evaluation of Multi-Organ Metabolism and Perfusion in Non-Alcoholic Fatty Liver Disease (NAFLD) by Total Body Dynamic PET Scan on EXPLORER

You are invited to participate in a research study that seeks to understand the effect of non-alcoholic fatty liver disease (NAFLD) on organs other than the liver. One of the most common organs affected in patients with NAFLD is the heart. We expect to have about 60 people participate in this study at UC Davis. About three-fourths (45) of the participants will be patients who have been diagnosed with NAFLD. The other one-fourth (15) will be healthy individuals with no known liver disease. These healthy subjects will allow researchers to compare healthy organs or body functions with those of persons with NAFLD. The healthy participants are called the "Healthy Control" group. All participants will undergo the same testing. If you agree to participate in this study, researchers will first interview you and review your medical records in order to document your medical (clinical) history. You will also have a physical examination by a doctor and a blood test. You will then undergo a series of imaging tests to determine the status of your liver, heart and other internal organs. All participants will have a PET/CT Scan (Positron Emission Tomography), and an MRI (Magnetic Resonance Imaging). All participants will also have an Electrocardiogram and an Echocardiogram. All Electrocardiogram tests are the same, but there are two types of Echocardiogram tests. One is like a standard ultra-sound imaging of your heart. The other is a "Stress Cardio" that will require you to increase your heart rate on a treadmill before the ultra-sound test. Your study doctor will determine which test you have.
