Evaluation of an international telepathology system between Boston (USA) and Dijon: glass slides versus telediagnostic television monitor.

A telepathology network developed by Resintel (Dijon) has proved valuable in interactive situations, where two physicians converse by telephone, showing each other the part of the lesion they wish to discuss. In future this interactive process could be replaced by an electronic mailing service in which a limited number of images are taken from the slide, but this technique needs to be assessed in comparison with traditional microscopic diagnosis, when the pathologist can screen the entire slide. The present study compared diagnoses achieved through the traditional methods of current pathology practice with diagnoses achieved through a selection of images on a telediagnostic TV monitor. The kappa coefficient between the two protocols was 0.26 (SE = 0.06), which allows us to conclude that there is a fair reliability between video and glass slide diagnoses.
