Factors influencing distant tele-evaluation in cytology, pathology, conventional radiology and mammography.

The present paper summarizes our 1 year's experience with the use of static high resolution videophones (9600 bauds transmission rate, lossless compression, 512 x 512 spatial resolution). The images (n = 610) belong to regular videoconsultation in cytology (160 images), (160 images), pathology (226 images), conventional radiology (50 images) and mammographies (174 images). The results showed an exponential relationship between agreement with 'gold standards' (true diagnosis of the case based on pathology, surgery and follow-up) and the time of training on screen diagnosis (r = 0.
