Abstract

In order to raise the accuracy among radiologists, cases where evident lesions were undetected were presented. For each case of diagnosed advanced gastric cancer by group exam, indirect fluororadiography taken each year up to 3 years before diagnosis were read again. Among advanced gastric cancer cases diagnosed by group exam over 6 years from 2004 to 2009, 44 cases that received medical checkups at this facility from the time cancer was diagnosed until 3 years before, were determined as continuous examinations, and targeted for consideration. Cases where evident lesions were undetected were set as sample cases.<BR>The results of the consideration showed that in 20 (45.5%) out of 44 cases evident lesions were undetected. Cases at a higher rate were in the posterior wall and in type three. Even advanced gastric cancers, diagnosis can be made based on minor findings, such as indirect findings. Careful and detailed reading of an X-ray should be carried out with full understanding of these matters.
