This scan looks at brain function by demonstrating the amount of blood taken up by the brain cells. It can show if some parts of the brain are working more than or less than normal. For this test, we will insert a cannula into a vein in your arm and then lie you in a dark room to rest completely for 30 minutes. During this time, we will give you an injection of a radiopharmaceutical in through this cannula which will highlight your brain for the camera. We then ask you to sit in the waiting room for a further 20 minutes to ensure all of our injection absorbs into the brain. Scanning is then commenced for 20 minutes.
