[Gastroenterologic radiology--present status].

Diagnostic radiology is still of paramount importance in gastroenterology, although endoscopy has replaced radiological double contrast studies in certain instances. Sonography and computerized tomography have greatly enhanced diagnostic evaluation of the abdominal organs. Invasive techniques using radiology and endoscopy have optimized both diagnosis and therapy. Close cooperation between the various specialist groups in gastroenterology is urgently needed if optimal scientific progress is to be achieved.
