[X-ray Investigations in Intensive Care Units. Development, Organization and Methods (author's transl)].

From special care following surgery and from artificial respiration of polio patients the modern and very special intensive medical care has developed. At the same time the provisional "bedside radiology" was improved to one branch of clinical radiology with special organisation and methods of investigation. Importance and urgency of radiological information are requiring close cooperation of all medical branches.

[Optimal conventional radiodiagnosis of chronic renal failure (author's transl)].

Contemporary methods and risks of intravenous urography in the evaluation of chronic renal failure, are discussed. Differential diagnosis of "small" as well als of "large" kidneys is presented by analysing the contour of the organs and the configuration of the collecting systems. Illustrative cases are shown.

[The diagnostic scope of ultrasonography in renal pathology (author's transl)].

The accuracy of ultrasonography in the diagnosis of different pathological renal conditions is evaluated. Correlations were established to the findings on intravenous urography and selective angiography. Ultrasonography is suitable for the determination of the exact size and site of the kidney and, therefore, should be used routinely in the follow-up of renal transplant recipients.

[Endoscopy and radiological investigations of the stomach and duodenum. Alternative or complementary procedures? (author's transl)].

The results of radiological and endoscopic examination in 1,030 patients were compared. In one third of cases there was some discrepancy relating to a significant diagnostic finding (malignant process, peptic ulcer, polyp, stenosis or deformity, abnormal folds, diverticula or normal findings). In analysing false negative and false positive radiological diagnoses, the patients were divided into two groups (with or without a double contrast technique).
