What is a PET scan and how does it work?
A PET (positron emission tomography) scan is a type of imaging test that uses radioactive glucose (radiotracer) to see where cancer cells may be. Since cancer cells intake more glucose than normal cells, injecting some glucose into a vein can reveal where cancerous cells are in the body when scanned and examined with computerized images. 1 锘匡豢锘?/div>PET Scan: Cancer Staging and Treatment – Verywell Health
What kind of cancer can a PET scan show?
A variety of cancer cells become visible as bright spots in the images of PET scans. PET scans can help detect cancer and how far it has spread. PET scans can show solid tumors in the brain, prostate, thyroid, lungs, and cervix. The scans can also evaluate the occurrence of colorectal, lymphoma, melanoma, and pancreatic tumors.
What is a combination PET/CT scan?
A PET scan is a painless procedure that helps detect disease sooner than CT or MRI images. A combination PET/CT scan provides a more detailed look at organs and tissue. PET scans can ensure an accurate diagnosis and help your healthcare provider develop an effective treatment plan
What can a PET scan tell you about metabolism?
The PET scan uses a radioactive drug (tracer) to show both normal and abnormal metabolic activity. A PET scan can often detect the abnormal metabolism of the tracer in diseases before the disease shows up on other imaging tests, such as computerized tomography (CT) and magnetic resonance imaging (MRI).
