The PET scan works by creating images of the biological functions of the body to reveal disease states. Prior to the exam, patients receive an injection of a tiny amount of radioactive tracer, which emits signals as it travels through the body.
Our scans utilize a positron-emitting form of glucose, which allows mapping of metabolism. Brain PET imaging is useful in the evaluation of primary brain tumors, Alzheimer’s dementia and the localization of seizure foci within the brain.
– On the day of your exam, please go directly to the 3310 Richmond location. Please be sure to bring the signed order from your physician requesting the examination, and your insurance cards as well.
– You should wear comfortable, loose-fitting clothing for your exam. Metal objects can affect the image, so avoid clothing with zippers and snaps.
– Prior to your exam, you will be asked to sign an informed consent form.
– The technologist will inject the radioactive isotope into a vein or venous catheter.
– The technologist begins by positioning the patient on the CT table. As the study proceeds, the table will move slowly into the CT scanner. The CT portion of the scan is first, followed by the PET portion.
– The exam will take 15 minutes to complete.
– After the exam a report, CD with images and color images will be delivered to your physician, generally within 24 hours.
