Abstract
To evaluate the feasibility of an inexpensive, generally applicable video-conferencing system for frozen section telepathology (TP). A commercially widely available PC-based dynamic video-conferencing system (Picture-Tel LIVE, model PCS 100) has been evaluated, using two, four and six ISDN channels (128-384 kilobits per second (kbs)) bandwidths. 129 frozen sections have been analyzed which were classified by TP as benign, uncertain (the remark probably benign, or probably malignant was allowed), malignant, or not acceptable image quality. The TP results were compared with the original frozen section diagnosis and final paraffin diagnosis. Only 384 kbs (3 ISDN-2 lines) resulted in acceptable speed and quality of microscope images, and synchronous image/speech transfer. In one of the frozen section cases (0.7%), TP image quality was classified as not acceptable, leaving 128 frozen sections for the analysis. Five of these cases were uncertain by TP, and also deferred by frozen section procedure (FS). One more benign and three malignant FS cases were classified as uncertain by TP. Three additional cases were uncertain by FS, but benign according to TP (in agreement with the final diagnosis). In one case, FS diagnosis was uncertain ...Continue Reading
