Side Effects of PET scan
It may sound frightening to get a PET scan, but don’t be concerned. There is absolutely no risk involved with the nuclear medicine technique. Compared to other imaging methods like an MRI or CT scan, a PET scan provides pictures of the body’s biological processes and is more likely to identify disorders rapidly (computed tomography). PET scans are frequently unsettling since they call for the infusion of a radioactive tracer. The radioactive tracer is actually a mixture of sugar and a radioisotope with a very low dosage. Do PET scans have any negative side effects if radioactive materials are in reality being used?
Bio/Techno-Fear
Being so technologically advanced, a PET scan may seem a little science fiction or even Frankensteinian to some people. However, a PET scan is completely risk-free and has no known after-effects.
The radioactive substance that is injected into the body needs time to get to the location that is to be photographed in a PET scan. In order for the compound to reach the locations where pictures will be captured, it must first pass through the bloodstream for 40 to 45 minutes while the patient is still. Images are created from signals the tracer emits.
Risks
- A PET scan shouldn’t be performed on a pregnant woman since radiation can harm an unborn child. If you believe you could be pregnant, avoid getting a PET scan.
- Moms who are nursing. Since they won’t be able to resume breastfeeding for 24 hours after the test, nursing moms should also pump and conserve breast milk before the exam.
- Iodine or sugar substitute allergies, including those to aspartame and saccharin, should prevent PET scans or at the very least be disclosed to the doctor. For those who are allergic, a different compound formed of diluted barium might be used in place of the iodine, which is generally used to make the trace component together with glucose.
- Swelling and bruising A brief stinging sensation will be experienced after the trace ingredient injection, but it won’t remain. However, there is a chance that the area will bruise and swell.
Get Ready
Once more, there are no significant dangers related to PET scans. Patients must follow pre-orders for their test, though, just as they do for any surgery. Patients must fast for six hours prior to the test, but they must follow a low-carb, sugar-free, and caffeine-free diet the day before the visit. Blood sugar levels may change as a result of the test. Before getting a PET scan, diabetics should discuss any medicines with their doctors.
Summary:
The majority of patients are unaware that they are exposed to radiation every day just by going about their regular lives. Most of us will be exposed to radiation over the course of a year that is comparable to five to six X-rays—roughly the same as what is used in a PET scan.
At RMN Center Rohtak, we’re skilled at allaying patients’ worries and offer extra attention to individuals who have allergies or pre-existing diseases like diabetes. Nothing is overlooked when it comes to your care. Before any scan or test is done, your whole medical history is taken into account.
