Original Title: Tyktarmsundersøgelse med CT-kolografi – en medicinsk teknologivurdering
Authors' objectives: In order to provide a general foundation for decision making at department/functional unit level the authors have clarified the following issues with the aid of prospective paired, observer-blinded studies of CT colonography and colonoscopy: How can the patient best be prepared for the investigation? How is analysis of CT colonography images best performed? What is the diagnostic precision of CT colonography in detecting polyps and CRC compared with colonoscopy (sensitivity and specificity), including the interobserver variation and reasons for incorrect diagnoses in a Danish outpatient colonoscopy population? To what extent are abnormalities requiring further investigation or treatment detected outside the bowel? How do patients experience CT colonography, including pain and other discomforts, compared with colonoscopy? How cost-effective is CT colonography compared with colonoscopy when the marginal costs at the hospital are calculated taking into account the effectiveness of the investigation? What are the costs per detected polyp for CT colonography compared with colonoscopy? In which patients is CT colonography relevant – either as the primary investigation or as a supplement to colonoscopy? What level of experience is required of the radiologist and the radiographer/nurse for the investigation to be performed in a satisfactory manner?
