Background: In the standard method of upper gastrointestinal imaging in cancer mass screening, it is necessary to rotate quickly to the right three times at the beginning of the process in order to achieve uniformity in the barium coat thickness. But, in practice, we often experience cases in which it is difficult to perform this action. Subjects and Method: The capability of the quick three times rotations within 40 seconds was evaluated in the non-movie oriented subjects of 1,665 and the movie oriented subjects of 1,631. Results: 1,237 of the non-movie oriented 1,655 and 1,433 of the movie oriented 1,631 were able to be rotated successfully (74.3% vs 87.9%, p<0.01). The success ratio became lower with age in both groups. The movie orientation was significantly effective in the 75 years of age or younger, but especially in the 75 years of age or older subjects, the effect of orientation movement was minimal. Conclusion: The orientation movie enables a higher success ratio of the quick triple rotation. But it is a matter of debate whether to apply the standard method including the quick rotations equally to older subjects in the imaging of the gastric cancer screening.
