Out university hospital, includes a LAN (Local Area Network) and uses network services such as WWW(World Wide Web). We have constructed an MRI diagnostic reporting system on the Internet in which interactive date management was established on WWW by using CGI (Common Gateway Interface) software.

This system suggests the possibility of creating a cheaper and more flexible network using Internet technology.
