[A comparison between radiologic and endoscopic examinations of early cancer of the stomach (author's transl)].

Comparison between radiologic and endoscopic-bioptic examinations shows that, in early cancer, great demands are made on the radiologic technique and experience of the examiner. An integrated technique using relief- and double-contrast with additional induced hypotony can achieve demonstration of circumscribed shallow changes of less than 2 cm diameter in all segments of the stomach. With this technique over 80% of early cancers can be detected radiologically.
