PET (Positron Emission Tomography)/CT Scan
Thank you for choosing UR Imaging. We look forward to serving your medical needs.
A PET scan utilizes a particular substance called a radioactive tracer which, when it enters the body, becomes absorbed into the body’s organs and tissues. The PET scanner highlights the tracer, revealing information as to how well the organs and tissues are functioning. This type of scan is used most commonly in the detection of cancer, heart conditions, brain abnormalities and complications with the central nervous system.
PET scans are performed simultaneously with CT scans, which reveal the location of diseases within the body. A PET/CT study combines the benefits of these two types of scans into a single exam.
You should be contacted at least 48 hours prior to your procedure to confirm your exam date and time, review instructions on how to prepare, and answer any questions you may have regarding the procedure. If you have not been contacted 48 hours before your exam, please call (585) 784-2985. If you need to cancel or reschedule your appointment, please call at least 24 hours before your procedure. The radiopharmaceutical used for this test is purchased 24 hours prior to testing and cannot be returned, saved or used on another patient.
We ask that you call at least 3 days ahead if any of the following pertain to you so we may make the appropriate modifications to your treatment plan:
- If you believe you may be pregnant, you are nursing or you are claustrophobic.
- If you have had a contrast allergy/reaction (i.e., hives, rash, itching, breathing difficulty) while undergoing a previous imaging study.
- If you are taking diabetic medication.
- University Medical Imaging (UMI), so prior images may be requested for comparison.
