Structured data entry-in which information is entered by using predete
rmined data elements and formats - has the potential to improve the ra
diology reporting process, The dependence on particular computer hardw
are and software platforms has posed a barrier to wider use of this ap
proach, The World Wide Web (WWW), a client-server protocol for deliver
y of multimedia data via the Internet, was used to achieve platform-in
dependent structured entry of radiology reports. A developmental syste
m for structured entry of radiology reports, called SPIDER, incorporat
es a knowledge base of hierarchically organized concepts, a WWW server
, and two specialized programs, The WebForm program transforms the sys
tem's knowledge into graphical WWW data-entry forms; the WebReport pro
gram converts data entered on these forms into outline-format reports,
SPIDER received favorable evaluations from sonographers and physician
s who used the system to record the results of several test cases. WWW
technology can be used to achieve platform-independent entry of the r
esults of radiologic procedures.
