Internet is an international computer network that uses standard communication protocols for the exchange of information. This facilitates the retrieval of multimedia data through a "web" of servers distributed in the whole world. Among Internet users, Radiologists are a potentially important segment, due to the inherent multimedia characteristics of the discipline, which requires a continuous international update of information. The Department of Radiology of the University of Pisa has an Internet access through the metropolitan area network which was installed in the framework of the CNR Telecomunicazioni Project. The Internet access allowed the implementation of a World Wide Web server made public on Internet in March, 1994, being the first European server specifically oriented to radiology. This server can be accessed at the following address: http:@www.rad.unipi.it:7080/IRMosaicHome.html . On the server, 3 hypermedia papers are present, a list of international servers containing radiological information, a questionnaire, and statistics concerning the number of users who accessed the server. In the first 18 months of public access through Internet (April 1, 1994-September 30, 1995) 16,166 users accessed the server, retrieving 127,349 documents, corresponding to 1,279.7 MByte of information. The mean amount of information retrieved in each access to the server in the considered quarters ranges from 72 to 85.8 kByte. The geographic distribution of the users who accessed the server is the following: United States, 7,158, Italy, 2,466; other European countries, 3,813; other extra-European countries, 2,729. The increasingly diffuse knowledge of Internet services had a substantial impact on the rise in number of the servers and of the users who can access them. It is likely that in the future this technology will be used with increasing interest by Radiologists, since it provides easier "navigation" through multimedia information, consisting of text and several images, without the inherent limitations of the printed paper.
互联网是一个使用标准通信协议进行信息交换的国际计算机网络。这使得通过分布在全球的服务器“网络”来检索多媒体数据变得更加便利。在互联网用户中，放射科医生是一个潜在的重要群体，因为该学科固有的多媒体特性要求信息不断进行国际更新。比萨大学放射科通过在国家研究委员会电信项目框架内安装的城域网接入互联网。1994年3月，通过互联网接入实现了一个万维网服务器的公开，这是欧洲第一个专门面向放射学的服务器。该服务器可通过以下地址访问：http:@www.rad.unipi.it:7080/IRMosaicHome.html 。服务器上有3篇超媒体论文、一份包含放射学信息的国际服务器列表、一份调查问卷以及有关访问该服务器的用户数量的统计数据。在通过互联网公开访问的前18个月（1994年4月1日至1995年9月30日），有16166名用户访问了该服务器，检索了127349份文档，相当于1279.7兆字节的信息。在所考虑的几个季度中，每次访问服务器检索到的信息平均量在72至85.8千字节之间。访问该服务器的用户的地理分布如下：美国7158人、意大利2466人、其他欧洲国家3813人、其他欧洲以外国家2729人。互联网服务知识的日益普及对服务器数量以及能够访问这些服务器的用户数量的增加产生了重大影响。未来，放射科医生可能会越来越多地使用这项技术，因为它能更轻松地“浏览”由文本和多幅图像组成的多媒体信息，而没有印刷纸张固有的局限性。
