[The diagnosis of intracranial tumors by CT (computerized tomography) from a practical point of view (author's transl)].

In a historical abstract the mathematical basis of image reconstruction techniques and CT is reviewed. The enhancement of iodine contrast media is essential in CT diagnostic of space occupying intracranial lesions. Intracranial tumors usually show relatively characteristical but mostly non-specific absorption patterns. Additional clinical information is necessary for differential diagnostic evaluation. The development of tables with various tumor patterns is recommended. Absorption feature of primary and secondary brain-tumors with the surrounding edema is explained. Glioblastomas as well as metastases often show a distinct cerebral edema which has been observed in 64% of our patients with metastases and distinctly localized high dense foci in 69%. 6000 patients were investigated by CT and 1708 examinations were performed with contrast enhancement of other intravenously applicated contrast media.

[Urogenital-tuberculosis: pathogenesis, diagnostic approach, roentgenologic pathology, staging and remarks for differential diagnosis (author's transl)].

The diagnostic tactics in the clarification of urogenital tuberculosis are referred to the changes for the individual examinations mentioned. Some tables show the results of radiological investigations on 200 patients with proved renal tuberculosis, the extend of the triple staging proposed by us being specified. In addition to expositions on the radiopathology of urogenital tuberculosis, the differential diagnosis is indicated, its focus lying in the comparsion of 118 patients with clinical-bacteriological and/or histologically confirmed non-specific chronic pyelonephritis. The comparison of patients from two 3-year groups 1959-1961 and 1971-1973 as well as between natives and foreigners shows a change in the clinical radiological picture of renal tuberculosis.

[Volumetric follow-up measurements in normal and pathologic lymph nodes (author's transl)].

Alteration of Lymph node volume are measured in different groups of patients. Irradiated Lymph nodes diminish volume significantly more and faster than non-irradiated ones. Lymph nodes with reactive hyperplasia with/without irradiation show a significantly smaller volume decrease than normal Lymph nodes. Malignant systemic diseases have a significant higher volume decrease than normal or reactive hyperplastic Lymph nodes with identical irradiation-dose.

[Value and limits of different method in diagnosis and differential diagnosis of retroperitoneal tumors within the lymphatic systems (author's transl)].

The demonstration of retroperitoneal intralymphatic primary or secondary tumors requires a progressive radiological investigation beginning with simple methods and advancing to more complicated ones. Radiological lymphography is a method which is superior due to its ability to demonstrate small structures in lymphatic vessels and lymphnodes. However, the usefulness of lymphography is limited partially to the retroperitoneal lymphatic system and to gross changes. To improve diagnostic accuracy further diagnostic measures are needed, namely intravenous urography, venocavography, lumbar venography of catheter, sonotomography of the upper abdomen and lymphatic scintigraphy. Exstirpation of lymphnodes- possibly by explorative laparotomy- and histopathological examination enables an extact assessment of lymphnodes of microscopical dimension as determination of the tumor type. The value and limits of complementary methods and the criteria for the diagnosis and differential diagnosis of metastatic lymphnodes and lymphoreticular systemic diseases are discussed. The significance of lymphography for evaluation of topographic expansion of pathological lymphnode changes, the further course of the disease and the effect of therapy according to the authors' experience are presented. It is stressed that the value of lymphography in diagnosing the type of disease is limited.
