The Coalition for PET Drug Approval is working with members of the medical community to make sure that drugs used when performing a PET scan are licensed by the FDA. In order to do a PET scan you must use a PET drug. If you are not sure what a PET scan really is we are providing information that will help you better understand. Our objective is to help the medical community to be able to continue to offer this very valuable diagnostic tool by helping manufacturers who produce the PET drugs to be able to continue to do so.
