- SPECT scan—You will be given an injection of a substance that will make the pictures of your brain clearer. You will lie on a table, and a camera-like object will slowly rotate around you. This test may take about 90 minutes or longer. Your doctor may choose to use a specific type of scan, called dopamine transporter scan (DATscan), to evaluate your condition.
