Presently most Nuclear Medicine physicians are well trained to report PET FDG studies. However, only a very limited number of them are able to diagnose difficult, unusual cases. For this reason, we developed an electronic lightbox called POSITOSCOPE onto which PET studies can be downloaded, displayed, reported and sent to remote sites for expert advice. To promote its use, we emphasized user-friendliness which is a keypoint of the prototype: the POSITOSCOPE looks like a classical lightbox equipped with a small touchscreen and a digital sound recorder. It is connected to local PET scanners and long distance high speed networks. Difficult studies can thus be sent to remote experts. The request consists of the whole image data set and a soundtrack explaining its nature. It may be sent to one or more experts. At this stage, only the local physician is responsible for reporting even though (s)he makes use of remote expertise. The prototype is being tested in two hospitals and the clinical evaluation involving four University hospitals and one private practice Nuclear Medicine center, started last September. Our goal is not to have PET studies acquired in a local center and to have them reported in a remote reference center, but to provide remote expertise when necessary to improve daily reporting of PET studies and to improve the expertise of local Nuclear Medicine physicians. The concept may be easily extended to unusual single photon studies for which local expertise is not always available, and to multimodality studies.
