Abstract
Combined PET-CT scanners have been in production for over 10 years, and the technology has undergone rapid evolution. For PET, the introduction of new scintillator materials, detector concepts, and electronics is resulting in performance improvements in count rate, spatial resolution, and signal-to-noise. At the same time, the increasing number of detector rows and reduction in rotation time are transforming whole-body CT performance. The combination of high performance CT with high performance PET is a powerful imaging platform for the diagnosis, staging and therapy monitoring of malignant disease. A 16-slice CT scanner should be adequate for most oncology applications, with a 64- or 128-slice CT more appropriate for PET-CT applications in cardiology. As the current PET-CT technology becomes more widespread, appropriate future designs of this concept will doubtless emerge.
