More could be covered if deemed necessary by the doctor.

If you need pain medication please bring it with you. You should plan on being at the imaging facility for approximately 2 to 3 hours. Is PET safe? The risks associated with a PET scan are very minimal.
All molecular and nuclear imaging procedures are very safe. PET imaging is a nuclear imaging procedure. They are noninvasive which eliminates many various risks. Radiation exposure is minimal in nuclear imaging procedures due to the fact that the amount of radiopharmaceutical used is extremely small.
The amount of radiation in most nuclear medicine procedures is comparable to that received during a CT scan. Family members are not at risk for exposure since most of the radioactivity has left the body or decomposed before the patient has left the center. What happens after my scan? Once the PET scan is complete, you will be able to leave the imaging facility.
