Official title
PET Evaluation of Brain Peripheral Benzodiazepine Receptors Using [11C]PBR28 in Neurological Disorders
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This study will use positron emission tomography (PET) imaging to measure a receptor in the brain that is involved in inflammation. Certain neurological disorders, possibly including frontotemporal dementia (FTD), are associated with increased inflammation in the brain. This study may help elucidate the relationship between FTD and inflammation. Patients with FTD and healthy volunteers who are 35 years of age or older may be eligible for this study. Candidates are screened with a medical history, physical examination, electrocardiogram, and blood and urine tests. Participants undergo the following procedures: * Whole body PET scan: PET uses small amounts of a radioactive chemical called a tracer that labels active areas of the brain so the activity can be seen with a special camera. The tracer used in this study is \[11C\]PBR28. Before starting the scan, a catheter (plastic tube) is placed in a vein in the arm to inject the tracer. Pictures are taken for 1 hour. This short scan is done to determine if \[11C\]PBR28 binds to the subject s receptors, since a number of people do not have binding. Subjects who have binding continue with brain PET and MRI scans, described below. * Brain PET imaging: Before starting the scan, a catheter is placed in a vein in the arm to inject the tracer,\<TAB\> and another catheter is placed in an artery in the wrist to obtain blood samples during the scan. The subject lies on the scanner bed. A special mask is fitted to the head and attached to the bed to help keep the person s head still during the scan so the images will be clear. An 8-minute transmission scan is done just before the tracer is injected to provide measures of the brain that are helpful in calculating information from subsequent scans. After the tracer is injected, pictures are taken for about 2.5 hours, while the subject lies still on the scanner bed. * Blood and urine tests are done the day of and the day following each PET scan. * Magnetic resonance imaging (MRI): An MRI scan is done within 1 year (before or after) of the PET scan. This procedure uses a magnetic field and radio waves to produce images of the brain. The subject lies on a table that is moved into the scanner (a tube-like device), wearing earplugs to muffle the noise of the machine during the scanning process. The test takes about 1 hour....
