- BACKGROUND:Neuroendocrine tumours constitute a small group of malignancies; about 200 new patients are diagnosed in Norway annually. This article discusses problems associated with use of deoxyfluoroglucose (FDG) Positron Emission Tomography (PET) and other available options in patients with these conditions, as well as challenges related to introduction of new radiopharmaceutical agents.MATERIAL AND METHODS:The article is based on review of literature in connection with development of new guidelines for nuclear medicine examinations, supplemented with literature identified through a non-systematic search of Pubmed.RESULTS:A large proportion of these tumours grow slowly, and recent data show that 5-year survival is about 50 %. Neuroendocrine tumours are characterised by specific biochemical processes that enable tailoring of radiopharmaceutical agents for PET and consequently a more accurate diagnosis and improved follow-up of these patients.INTERPRETATION:As for other cancer types, diagnostics and detection of metastases are an important factor for correct treatment of neuroendocrine tumours. PET with FDG is of limited use for patients with this condition. New specific radiopharmaceutical agents for PET may imply detection of 90 % of all such tumours.

- The aim of this work is to identify the properties that a universal multidimensional input device should have in order to optimally function with 3D applications, including Web browsers, window managers, digital content creation software, and computer games. Such applications have become increasingly effective due to the rapid development of computer graphics. This situation has generated a greater need for multidimensional input devices. It is conjectured that an ideal universal multidimensional input device should allow for 2D pointing as well as precise manipulation and navigation within 3D environments. Accordingly, the device should offer (a) six degrees of freedom, (b) a range of motion adapted to finger manipulation, (c) elastic suspension providing rich sensory feedback, and (d) position and rate control. The input device, SpaceCat, was designed to offer all these properties. Although such devices are known to benefit 3D navigation, this work demonstrates that they also benefit 3D object manipulation.
