This study looks at the effects of GLP-1 receptor agonist (GLP1-RA) medications such as Zepbound, Wegovy, etc. on muscle health in adults with obesity. This will be evaluated using an MRI scan before starting a GLP-1 RA and after losing 10% of body weight on the GLP-1 RA.
Specific Aims include: Coordinate all human PET and MR imaging at U Penn, UCSF, Yale and WU. Standardize inclusion/exclusion criteria for patient groups - idiopathic PD, MSA, PSP, FTD and healthy controls. Harmonize PET scanning protocols and devices. Generate and coordinate all regulatory protocols including local Radiation Safety or Radioactive …
The purpose of the study is to determine the changes in muscle metabolites by MRI before and after exercise. The MRI will be performed while performing mild exercise of the calf muscle for 1-3 minutes. We are actively recruiting adults between 45-55 and 70-84. Volunteers cannot have diabetes, liver disease, kidney …
This study investigates the changes in the brain that occur in the first three years following a traumatic brain injury (TBI). The purpose of this study is to compare the rate of brain tissue loss in individuals with TBI to those without, using healthy participants as a control group.Participants in …
Primary Objectives Determine biodistribution of the radioactive investigational drug, 11C M503 and calculate human dosimetry (at least 10 male and female participants). Demonstrate the feasibility of imaging the brain with the novel imaging agent 11C M503 Determine the most appropriate data analysis methodology. Determine whether there is selective uptake of …
This study investigates fibrotic conditions. It uses Fibroblast Activating Protein (FAP) PET/CT imaging to look at fibrosis caused by different medical conditions.The study evaluates if this imaging method can show how fibrosis affects major organs and tissues. It focuses on understanding the distribution of FAP in the body.Who can participate: …
Primary Objectives Determine biodistribution of the radioactive investigational drug, 11C HY-2-15 and calculate human dosimetry (at least 10 male and female participants). Demonstrate the feasibility of imaging the brain with the novel imaging agent 11C HY-2-15 Determine the most appropriate data analysis methodology. Determine whether there is selective uptake of …
This study investigates myocardial glucose suppression in FDG PET/CT scans. The purpose of this study is to evaluate the effect of sodium-glucose cotransporter-1/2 inhibitors on glucose levels in the heart.The study evaluates the safety and effectiveness of combining a ketogenic diet with an investigational medication to enhance imaging results. Researchers …
To assess whether next-generation photon-counting CT, which enables reduced radiation dose, high spatial resolution, and spectral imaging, would facilitate improved diagnostic performance for abdominal, cardiothoracic, musculoskeletal, and neuroimaging. To verify the accuracy and establish the fundamental efficacy of additional information made available by PCCT. Quality of images.
This study investigates the presence of certain brain proteins in people with conditions like Progressive Supranuclear Palsy, Corticobasal Syndrome, genetic Frontotemporal Lobar Degeneration, Parkinson's Disease, Alzheimer's Disease, and healthy individuals. These conditions are collectively known as tauopathies.The study evaluates how a special substance, which can be seen in brain scans, …
