What is a PET/CT scan and how does it help cancer patients?
By combining information about the body’s anatomy and metabolic function, a PET/CT scan provides a more detailed picture of cancerous tissues than either test does alone. The PET and CT images appear in a single scan, allowing for a high level of accuracy. The use of PET/CT scan helps the oncology team develop the optimal cancer treatment plan.
What is a PET-CT scan?
This is known as a PET-CT scan. They may also occasionally be combined with an MRI scan (known as a PET-MRI scan). A PET scan can show how well certain parts of your body are working, rather than simply showing what they look like.

The image on the right is a combined PET-CT scan. The bright spot in the chest, seen best on the PET and PET-CT scans is lung cancer. Cancer cells show up as bright spots on PET scans because they have a higher metabolic rate than do normal cells.
What is the difference between PET/CT and PET/MRI?
Compared with an X-ray or magnetic resonance imaging (MRI) scan, a PET/CT enables doctors to examine medical conditions and abnormalities at a cellular level. What is PET/MRI? A PET/MRI scan is used to obtain anatomic and quantitative information from an MRI at the same time as physiologic information from PET imaging.
