Positron emission tomography: a technology assessment of PET imaging--past, present, and future.
Emerging from its origins in the basements of research laboratories, positron emission tomography (PET), has established itself as a premier clinical imaging modality. It just took 50 years to get there. PET and the ever-popular, dual imaging modality combination of positron emission tomography/computed tomography (PET/CT) have taken hold of the spotlight at the national meetings of the Radiological Society of North America (RSNA) and the Society of Nuclear Medicine (SNM)--and they are not about to give it up. Many major imaging manufacturers--those companies that make up the majority of imaging sales in the US--now offer some type of PET and or PET/CT scanner. The technology of PET imaging continues to improve in image resolution, speed, and acceptance by its skeptical, but continually growing, referral base. With the increasing number of regional cyclotron facilities throughout the US each year, the abundance of mobile PET companies competing for business, and, most important, the number of clinical procedures that now qualify for reimbursement, more facilities now have the ability to implement PETimaging. This article discusses the progress of PET, from its beginnings 50 years ago, to where it is today--and the direction it is headed in the future.
