[Diagnostic radiology for tumors for the small intestine(author's transl)].

The fractionated gastrointestinal tract presents technical problems which result in a large number of diagnostic errors in regard to tumors of the small intestine. Pharmacoradiologic processes and Sellink's sounding method deal successfully with these problems. The methods were described and their advantages for tumor diagnostics in the small intestine were stressed. The mesenteric angiography is important as an alternative and supplementary examination for small intestine diagnostics. Indications and interpretation possibilities were described.
