There is increasing attention about radiology teaching files on the Internet in the field
of diagnostic radiology. The purpose of this study was to aid in the creation of new
radiology teaching file by analysing the present radiology teaching file sites on the
Internet with many aspects and evaluating images on those sites, using Macintosh ¥±ci
computer, 28.8kbps TelePort Fax/ Modem, Netscape Navigator 2.0 software
The results were as follow :
1. Analysis of radiology teaching file sites
(1) Country distribution was the highest in USA(57.5%).
(2) Average number of cases was 186 cases and radiology teaching file sites with
search engine were 9 site 5 (22.5%).
(3) At the method of case arrangement, anatomic area type and diagnosis type were
found at the10 sites(25%) each, question & answer type was found at the 9
sites(22.5%).
(4) Radiology teaching file sites with oro-maxillofacial disorder were 9 sites(22.5%).
(5) At the image format, GIF format was found at the 14 sites(35%). and JPEG
format found at the 14 sites(35%).
(6) Created year was the highest in 1995(43.7%).
(7) Continuing case upload was found at the 35 sites(87.5%).
2. Evaluation of images on the radiology teaching files
(1) Average file size of GIF format (71 Kbyte) was greater than that of JPEG
format(24 Kbyte). (P<0.001)
(2) Image qaulity of G9 format was better than that of JPEG format. (p<0.001)
