Abstract:	Objective: Three-dimensional (3D)-imaging has revolutionized both radiological diagnosis and surgical planning. It enhances the assessment of anatomical structures and is helpful for preoperative planning. Several studies have described that 3D images enhances the assessment of anatomical structures. The aim of this cost-utility analysis (CUA) was to assess the utility and the cost that has to be spent per value gained by 3D-imaging from the perspective “surgeons”. In addition the type of 3D service demanded by surgeons was assessed. Methods: To measure utility ten different statements were weighted by an expert team. Afterwards they were sent to surgeons working in Switzerland, who answered the questions using a 4-point score for imaging with and without 3D-reconstruction. The resulting score was multiplied by the weighting factor and user-related weighting factors (experience and usage). The costs were calculated on the reimbursement for 3D-imaging charged until the beginning of 2008 in Switzerland. In addition ten statements concerning 3D imaging services were added. Results: The majority (45%) only had a moderate experience regarding 3D-reconstruction. Only 26% used 3D-imaging on a regular base. The total utility showed an increase of 706 points (8.5%). The use of 3D-imaging let to a total percentage change of answers over all statements of 56% (score 3 to 4) and 52% (score 2 to 3). It enhanced especially the preoperative planning (+18% resp. +164 points). There was no improvement for intraoperative navigation, but had a high benefit to define operation strategy. The price per reconstruction is CHF 96 per exam, which lower than the suggested price (CHF 100-150). The cost per gained 10 utilities for the three different types was CHF 1.36. Concerning the services two points were important: 3D images should be made solely by radiologist itself and 3D images should be manipulable. Conclusion: 3D-images have an increased utility for preoperative planning. But further spread and improvement of 3D-imaging is not possible without a close collaboration between surgeons, radiologists and engineers. The ongoing refinement of surgical techniques towards minimal invasive approaches will power the development of new tools including preoperative simulation.
