[The radiological examination of the detailed relief pattern of the stomach part 4 (direct comparison of the pattern in the pyloric canal with the histological findings as related to the problem of chronic gastritis) (author's transl)].

Following earlier work on the relationship between the micromucosal pattern of the stomach and chronic gastritis, a comparison was carried out between the appearances in the pyloric canal and the histological findings in that area. The presence of chronic gastritis could not be excluded, irrespective of the type of relief pattern. Normal gastric mucosa was only found in areas showing medium sized areae gastricae. Fundamental problems concerning the radiological technique are discussed as well as the evidence for the diagnosis of chronic gastritis.
