How often should you get PET scans?
In practice, many doctors do CT scans of the body and pelvis every few months; others do nuclear medicine tests such as PET scans or bone scans.
Many patients also demand them.
There is no evidence that these tests and early detection of tumor growth benefit the patients, but many doctors do them anyway.
How many PET scans can you have in a lifetime?
“With the CMS requirement that there be no more than three PET/CT scans covered after the first line of treatment, that’s looking at it in a depersonalized way that may be harmful to patients on an individualized basis,” Copeland says.
Do all cancers show up on a PET scan?
PET scans detect areas of activity (like cell growth) in the body. More radioactive material collects in cancer cells than normal cells and will appear brighter on the image. Not all cancers show up on a PET scan. PET scan results are often used with other imaging and lab test results.
How long are you radioactive after a PET scan?
However, because radioactive material will remain in your body for about 12 hours, you’ll want to limit your contact with both pregnant women and infants during this time. Drink plenty of fluids after the test to help flush the tracers out of your system. Generally, all tracers leave your body after two days.
