The test involves an injection of a radioactive tracer (18F – FBB) which is a positron emitter. This 18F – FBB can detect the presence of amyloid plaque groups, which are a hallmark of Alzheimer’s disease. During this service, you will undergo an uptake period in your own private room, and then complete a brain scan after.

18F – FBB is not only specific to the brain but can also be found in normal healthy organs such as the heart, stomach, salivary glands, bone marrow, spleen and kidneys. Although these organs will receive some of the radiation, clinical trials have not demonstrated significant impacts from this compound. (2)
