PET/CT SCAN

What is a PET/CT Scan?

This is a diagnostic imaging study that combines the best features of positron emission tomography (PET) and computed tomography (CT). PET scans can pinpoint a disease on the cellular level and CT scans record images of the body on a ring of detectors. Together they can produce a series of images that don't show up on conventional scans.

PET + CT

Combining a PET scan with an MRI or CT scan help make the images easier to interpret. The image on the far left is a CT scan, while the center image is from a PET scanner. The image on the right is a combined PET/CT scan. This image clearly shows where the bright spot on the chest is located and where that particular incidence of lung cancer is located in relation to other organs.

The wealth of information that a scan provides may enable your doctors to confirm that your treatment is working, or switch you to a more effective treatment immediately.

FAQ

A positron emission tomography (PET) scan is an imaging test that uses a radioactive substance called a tracer to look for disease in the body. A PET scan shows how organs and tissues are working.

This is a diagnostic imaging study that combines the best features of positron emission tomography (PET) and computed tomography (CT).

A PET/CT study helps your physician diagnose problems, pinpoint the best approach to treatment, and monitor your progress. If you're not responding as well as expected, you can be switched to a more effective therapy immediately.
And once your course of care draws to a close, PET/CT monitoring can give you the peace of mind of knowing that your treatment was successful.
This entire process will take approximately three hours.
A small amount of sugar, called fluorodeoxyglucose (FDG) is injected into a vein. During the study, different amounts of FDG are absorbed by healthy and diseased cells. Unhealthy cells absorb more and produce gamma rays, which allow a computer to pinpoint and find areas of disease on the cellular level.
You may leave as soon as the scan is complete. Unless you've received special instructions, you'll be able to eat and drink immediately - drinking lots of fluids will help remove any of the radiopharmaceutical that may still be in your system. In the meantime, your results will be prepared for review and the findings forwarded to your physician, who will tell you what has been learned.
