Yes, it's generally safe to be around people after a PET scan, but as a precaution, you should limit close contact (like cuddling or sitting on laps) with pregnant women, babies, and young children for several hours (usually 6-24 hours), as advised by your doctor, because of the temporary, low-level radioactive tracer in your body. You can typically resume normal activities and driving (unless sedated) but should follow specific instructions from your healthcare provider for handling the residual radiation.
After a PET scan
But the radiographer will advise you not to have close contact with pregnant people, babies and young children for 24 hours after the scan. After this, the radioactive substance will have been passed out in your urine (pee).
Limiting contact with others after a PET scan is advised due to the radioactive tracer used. The PET scan is a diagnostic tool that uses a small amount of radioactive material. Radiation safety is a concern post-PET scan to minimize exposure to others.
Millions of PET scans have happened around the world without complications. The amount of radiation administered is small and will pass out of the body in urine. By the end of the day, most of the radioactive sugar (FDG) will be out of your body. There is no need to distance or isolate yourself from other people.
Certain factors or conditions may interfere with the accuracy of a PET scan, including:
AFTER COMPLETION OF PROCEDURE
You should avoid exposure to small children or pregnant women for six (6) hours. Any amount of radiation exposure to a child should be avoided as much as possible.
As a precaution, you may be advised to avoid prolonged close contact with pregnant women, babies or young children for a few hours after a PET scan, as you will be slightly radioactive during this time.
Keeping a safe distance and limiting close contact helps lower others' exposure. Here's a good rule: Keep at least 3 feet from others, like kids and pregnant women, for 24 hours after the scan. Avoid hugging or kissing for at least 6 hours after the scan.
Yes, you can be with other people after your scan. There is a very small amount of radiation in your body that is not harmful. Some doctors, though, may tell you to stay away from babies and pregnant women for a few hours just to be safe. This is just a safety measure, not because the radiation is harmful.
The radioactive dye used in PET scans can be harmful to your cat or dog (just as it is to children). Stay away from your pets for six hours after receiving a PET scan.
You will be asked to follow the Limited Carbohydrate diet for the previous 24 hours before the date of your appointment. Do not eat or drink anything, except water, for 6 hours before the exam. You may drink water, as much water as you can would be helpful, until arrival.
Driving. It's safe to drive and to go back to work, if you choose, after the PSMA PET scan. But if you received medicine to help you feel more comfortable during the scan, it may not be safe to drive. You will need someone to take you home.
One can have a seat in the PET/CT Suite Waiting Room, while we get a room ready for your scan. After the test, you are required to maintain a safe distance of 10 feet from both children and pregnant women.
After the test, your body will produce a small amount of radiation for a short time. Regular handwashing and showering can help limit radiation exposure to people around you. It is generally advised to avoid close contact with children and newborns for 1 to 2 days after a nuclear stress test.
After your PET scan, a very small amount of the radiotracer will remain in your body. So, be sure to drink plenty of water to help flush it out of your system. You may eat and use the restroom as usual after your scan. A specialist will review your PET scan and share the results with your doctor.
After a PET scan
The radioactive material passes out of the body through urine or stool (feces). It may take a few hours or days to completely pass out of the body. Drink lots of fluids after the test to help flush it out.
As a precaution you should avoid contact with pregnant women and small babies for six hours after your scan.
The radiation from the tracer drops to a safe level quickly and will be gone from your body within a few hours. Drinking plenty of fluid will help flush it from your body. For safety, after the scan you'll need to avoid spending a long time or having close contact with young children or anyone who is pregnant.
After a PET scan, it's important to limit close contact with others. This is to keep everyone safe. The scan uses a radioactive tracer that can release radiation.
Drink plenty of fluids and try to urinate as often as possible. This will help eliminate any residual 18F-FDG from your body and reduce radiation exposure. When using the bathroom, make sure that you flush the toilet twice and that any spilled urine is wiped up and the tissue is flushed down the toilet immediately.
After an FES or FDG PET scan
You can start eating your regular diet right away, unless your doctor gives you other instructions. It's safe to be around people who are older than 18. You can spend time near others, kiss, hug, hold, and touch them. If you're breastfeeding, stop breastfeeding for 12 hours after the scan.
In general, PET scans are safe and rarely cause problems. The amount of radiation in the radioactive tracer is very low. It doesn't stay in your body for long. You should drink lots of water after a PET scan to help flush the radioactive drug from your body.
Air travel after your PET-MRI scan
Airports have sensitive radiation monitors that might pick up traces of radiation after your test. As a precaution take your appointment letter with you if you're travelling within a week of your scan.
It involves putting a radioactive tracer into your body, which can lead to various physical and emotional reactions. Patients often experience after PET scan feelings such as anxiety or uneasiness while waiting for results. Some might also feel fatigued or dizzy because of the tracer.
