Is exercising Before a PET scan Risky?

(February 25, 2013)

Exercising before a PET scan is inadvisable as it can affect the scan results and give a false-positive result. In fact, specialists in nuclear medicine say that any type of activity, including jogging on the previous day can affect the results of a PET scan.

For this reason it is important that the doctor who is taking your test know about any kind of extraordinary physical activity you may have undertaken in the 48 hours preceding the test. This will help the doctor interpret the results of the PET scan more accurately.

PET (positron emission tomography) is an imaging technique that is used to examine organs and other tissue. It is used as a non-invasive diagnostic tool in different medical specialties such as oncology and neurology.

Patients are instructed at the time of making their appointment to refrain from any extraordinary physical activity for 48 hours before the test. They are also instructed not to eat for at least six hours before the test. Heart patients should refrain from consuming caffeine for 24 hours beforehand. Diabetics will be given special instructions on the use of medications before the test.
