What is a SPECT brain scan?
This scan is for patients with epilepsy for seizure localization and to evaluate brain perfusion.
How should I prepare for a SPECT brain scan?
There is no prep for this exam.
How long does the test take?
This scan takes about 30 minutes and is typically performed two times. Once as a baseline where the radioactive isotope is injection while you are not having a seizure and another where it is injected while you are having a seizure. The injections are given in a different department where you will be assigned as an inpatient. After the injection you will be brought to the Nuclear Medicine Department for your scan. The scan takes about 30 minutes and you will be asked to lie flat on our imaging table and hold very still the entire length of the exam. There will be foam holders and a small band placed across your forehead to help you hold still.
How soon will the scan results be available?
A radiologist will interpret the images, write a report, and deliver the results to your doctor via the internal computer system. This process usually takes less than 24 hours.
It is essential to tell your doctor if you are pregnant or think you might be pregnant before undergoing this scan because of radiation exposure.
