Potential Side Effects of PET Scans
PET (positron emission tomography) scans help to deliver clear images of the biological functions of the body. They help to detect disease quicker compared to other imaging techniques like magnetic resonance imaging (MRI) or computed tomography (CT) scans. A PET scan is a highly technological nuclear procedure that is very safe with no known potential side effects. The risks for this procedure apply only to a few cases. The procedure requires the patient to be injected with a radioactive tracer, which is compounded with low dose radioisotope and sugar. The radioactive compound travels to the location being imaged while the patient rests still on the scanner for about 40 to 45 minutes. Once it reaches the cancer location, the tracer will emit signals, which will be translated into images by a computer. During cancer diagnosis, doctors want to look at all angles of the disease, including the possible causes and consequences. PET can be combined with other imaging techniqu
