Security aspects of teleradiology between the university centre and outlying hospitals in Tyrol.

We assessed a data security system using biometric fingerprint techniques and smartcards to control access to a teleradiology system. Clinical cases were initially discussed between the referring physician and radiologist in Tyrol using a video-phone. Subsequent correspondence, including the transmission of images between the referring physician and the radiologist, was carried out by e-mail using the security system to prevent unauthorized access to patient information.

[Controlled results of standardized X-ray examination technique (author's transl)].

2000 patients were examined in our hospital within a period of 1 1/2 years using a standardized technique of x-ray examination of the stomach. Of these examinations, the gastroscopic, histological and partly also surgical results are now available from 241 patients. Hypotonic double-contrast technique, a highly dense, low-viscosity barium preparation and standardized documentation by means of 12 to 14 images taken with a 100 mm camera, have proved successful.
