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 telenetwork 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.
我们讨论了挪威北部远程冰冻切片服务的组织情况。该服务通过对位于希尔克内斯医院的电动视频显微镜进行远程控制来运作，该医院距离特罗姆瑟大学医院的工作站超过400公里。冰冻切片的视频图像通过容量为2 Mbit/s的双向电话和视频远程网络传输。图像显示在监视器上，由特罗姆瑟的病理学家进行诊断。迄今为止，已有17名患者接受了远程冰冻切片检查。与基于福尔马林固定和石蜡包埋材料的最终诊断相比，所有17例病例均给出了正确的良性与恶性诊断。检查每个冰冻切片的平均时间为15分钟（范围为5至30分钟）。在任何病例中，都没有因为视频图像质量不足而导致对切片的解读困难。对于当地病理服务有限的小型医院以及缺乏专家的医院而言，远程病理学可能是一种值得采用的替代方法。
