As research advances in the area of Alzheimer’s disease, greater emphasis is being placed on the study of biomarkers. These videos are designed to help participants enrolled in our research studies understand why some studies include requests for biomarker procedures. The videos also offer a general overview of how the procedures are conducted.

The first two videos describe a PET (Positron Emission Tomography) scan, which is an imaging technique that uses a radiotracer and computer to create a detailed picture of what is happening inside the body. The next three videos describe an MRI (Magnetic Resonance Imaging) procedure, which is an imaging technique that uses a strong magnet, radio signal, and computer to produce detailed pictures of the inside of your body, as well as a lumbar puncture (LP), during which a clinician uses a needle to draw cerebrospinal fluid (CSF).
