[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.

[Radiologic diagnosis of bronchial cancer].

The significance of CT in the preoperative radiological diagnosis of bronchogenic carcinoma has been examined in 37 patients. Today it is possible to make a more accurate diagnosis regarding the following points: 1. The determination of the number and the localisation of peripheral tumors and metastases 2.

[Comparative scintigraphic and roentgenological examinations of the lung in various stages of silicosis (author's transl)].

In 84 patients with silicosis of various stages, a semi-quantitative topographical measurement of perfusion of the lung was performed with radionuclide albumin particles. At the same time, the scintigram of the lungs and x-ray films of the thorax were compared with each other. With increasing degree of severity of the silicosis, redistribution of the pulmonary blood flow was seen.

[The use of ultra-sound in sinus disease (author's transl)].

The inclusion of ultra-sound in the routine diagnosis of sinus disease reduces the margin of error by about 6%, compared to that using clinical records and x-ray. The investigator should have sufficient experience in operating the ultrasonic equipment. Especially valuable is the ultrasonic diagnosis in cases of discharge, mucosal swelling or tumor in the sinus, as well as in cases of sinus examination of children and for control of patients having had conservative treatment or operations.
