My entire medical team (RO, the nuclear medicine director . MO and ENT) think PET scans are "not quite ready for Prime time" (as the old original Saturday Night Live skit went)for Cancer Detection. They all feel that PETscans are invaluable for staging the radiation fields once the tumor is big but the routine false positives plus the inability to detect recurrence as early as a MRI (the even worse false negatives - like I had twice) are worrisome. Even the written radiologist reports of every PETscan I have had state clearly that there should be a follow up MRI to clarify "findings". I think I will be passing on them in the future since their track record with me is zero. Clearly patients like myself were not part of the glowing studies.
