The PET scan itself may take another 30 to 60 minutes.

Heart and brain studies take less time for imaging.

How does cancer show up on a PET scan?

PET Scans. PET scans, short for Positron Emission Tomography, can detect areas of cancer by obtaining images of the body’s cells as they work.

What is a PET scan used to diagnose?

A positron emission tomography (PET) scan is an imaging test that helps reveal how your tissues and organs are functioning. A PET scan uses a radioactive drug (tracer) to show this activity. This scan can sometimes detect disease before it shows up on other imaging tests.

Do all cancers show up on PET scan?

Not all cancers show up on a PET scan. PET scan results are often used with other imaging and lab test results. Other tests are often needed to find out whether an area that collected a lot of radioactive material is non-cancerous (benign) or cancerous (malignant).
