Telepathology is the technology currently available that allows transmission of gross and microscopic images to a remote site via telephone lines ( T or ISDN lines). This technology allows pathologists at remote locations to exchange images and consult with other colleagues via teleconferencing without having to actually send slides by mail. With current technology pathologists can make a diagnosis on about 97.5 to 98.5% of cases on their computer screens. All cases can and should be reviewed until a good level of comfort is achieved in diagnosing pathology by this methodology. Some programs will allow digitizing and clarifying the images to help improve the image quality.
