REMOTE FROZEN SECTION SERVICE - A TELEPATHOLOGY PROJECT IN NORTHERN NORWAY

We discuss the organization of a remote frozen section service in northern Norway. The service is operated by remote control of a motorized video-microscope located at Kirkenes Hospital, at a distance of more than 400 km from the workstation at the University Hospital in Tromsø. The video images of the frozen section are transmitted via a two-way telephone and video telenet-work with a 2 Mbit/s capacity. The images are displayed on monitors and diagnosed by pathologists in Tromsø. To date, 17 patients have been examined by remote frozen section. Correct benign versus malignant diagnoses have been given in all 17 cases compared with final diagnoses based on formalin-fixed and paraffin-embedded material. The average time taken for examining each frozen section was 15 minutes (range, 5 to 30 minutes). In none of the cases was the interpretation of the slides difficult due to deficient quality of the video images. For small hospitals with limited availability of local pathology services and for hospitals with a deficiency of specialists, telepathology may be a worthwhile substitute. © 1991.
