CT und MRT des Dünndarms

Zusammenfassung

Die MDCT und MRT besitzen einen festen Stellenwert in der Dünndarmdiagnostik. Der Beitrag liefert eine Übersicht über Technik und Indikationsspektrum sowie Vor- und Nachteile dieser Verfahren. Anhand einer Auswahl relevanter Dünndarmerkrankungen aus dem Formenkreis Entzündung und Tumoren sowie gastrointestinaler Blutung werden charakteristische bildmorphologische Befunde sowie Tipps und Tricks vorgestellt und in alltagstaugliche diagnostische Algorithmen eingebunden.

Abstract

MDCT and MRT are valuable methods for diagnosing small bowel diseases. This article provides an overview of the techniques, indication spectrum, and advantages and disadvantages. Characteristic morphological image findings and diagnosing tips and tricks are explained on the basis of a selection of relevant small bowel diseases including inflammation, tumours and gastrointestinal bleeding.
