1 Arts and Sciences Creating a report form of image reading by radiological technologists in population-based screening for gastric cancer Key words: Gastric cancer Population-based screening Barium study Image reading support Report form Abstract Some support for image reading by radiological technologists has been notified as a part of promoting team medicine. In order to such image reading support in population-based screening for gastric cancer, we have created a report form suitable for radiological technologists. The contents described in the report are evidence of judgment and categorization. If there are abnormal findings in images, the number of lesions and the location of lesions should be described in the report. In addition, the blanks for schema and comments are provided in order to writing property and morphology of the lesions. The prototype form of the report was evaluated by six of this study and 55 to the workshop, who were all radiological technologists. Based on their evaluations and comments on convenience to be used in population-based screening for gastric cancer, a proper report form has been made for the support of image reading by radiological technologists X Toshimasa Ogawa , Kenyu Yamamoto , Masahumi Takai , Takaaki Matsuoka 4 431, Satoshi Hosomi 5, Akane Shirahase 6 1 Butsuryo College of Osaka 2 Osaka Center for Cancer and Cardiovascular Disease Prevention 3 Saiseikai Shin-Sennan Hospital 4 Nakai Memorial Hospital 5 Kyoto Industrial Health Association 6 Midori Health Care Foundation 2 B X X 3 NPO X
