As part of the Choosing Wisely campaign, 17 additional medical societies including SNMMI have contributed recommendations to the American Board of Internal Medicine-led effort. SNMMI's recommendations address use of nuclear medicine and molecular imaging tests. The recommendations advise providers to refrain from using PET/CT to screen for cancer in healthy people and avoid PET imaging to assess patients with dementia unless the patient has been seen by a specialist. Other recommendations address cardiovascular and thyroid screenings. SNMMI President-elect Dr. Gary Dillehay said the procedures addressed in the recommendations weren't necessarily abused. "Times have changed on some of these things, and they (just) don't apply anymore," he said.
