HMPAO brain scan
This is a test to look at the blood supply to the brain. You will be given an injection in your arm of a small amount of radioactivity that settles in the brain. In order for the tracer to settle evenly, the injection will be done whilst lying quietly in a darkened room. This feels very similar to a blood test and has no side effects.
The images are taken soon after the injection. You will be asked to lie on your back on a bed with your head in a small cradle. Two cameras will move around your head to create images but they do not touch your head. The images take about 25 minutes to acquire.
After all the images are completed, the technologist will check them before you go home. We will not be able to give out the result of the study immediately but a written report will be sent to the referring doctor. There are no side effects from the test.
