A Review of Scientific Topics and Literature in Abdominal Radiology in Germany – Part 2: Abdominal Parenchymal Organs

Abstract

The working group for abdominal and gastrointestinal diagnosis is a group of the German Radiological Society (DRG) focusing clinically and scientifically on the diagnosis and treatment of the gastrointestinal tract as well as the parenchymal abdominal organs. In this article we give an up-to-date literature review of scientific radiological topics especially covered by German radiologists. The working group experts cover the most recent relevant studies concerning liver-specific contrast media with an emphasis on a new classification system for liver adenomas. Additionally studies regarding selective internal radiotherapy (SIRT) are reviewed. For the pancreas the most important tumors are described followed by an introduction to the most recently introduced functional imaging techniques. The manuscript concludes with some remarks on recent studies and concerning chronic pancreatitis as well as autoimmune pancreatitis.

Key Points:

• Different subtypes of liver adenomas with different therapeutic consequences can be differentiated by MRI

• Most recently published studies focus on liver imaging with extracelluar liver specific contrast media as well as diffusion weighted imaging. They consider this new method having a high diagnostic potential.

• For pancreatic neoplasm diagnosis diffusion – as well as perfusion – imaging is considered as a highly promising method.

Zusammenfassung

Die AG Abdominal- und Gastrointestinaldiagnostik ist die Arbeitsgemeinschaft der Deutschen Röntgengesellschaft (DRG), die sich klinisch und wissenschaftlich auf Diagnostik und Therapie des Gastrointestinaltraktes mit allen parenchymatösen Abdominalorganen fokussiert. Im vorliegenden Artikel wird eine aktuelle Übersicht forschungsrelevanter Themengebiete vor allem der deutschsprachigen Radiologie gegeben. Die Experten der AG fassen dabei die aktuellen Studien bezüglich leberspezifischer Kontrastmittel zusammen. Ein besonderes Augenmerk wird auf die neue Einteilung der Leberadenomtypen mit ihren typischen Erscheinungsformen in der MRT gelegt. Ergänzt wird die Übersicht mit einer Zusammenfassung relevanter Publikationen zur radiologischen intraarteriellen Therapie von Lebertumoren mit Fokus auf der selektiven internen Radiotherapie (SIRT). Im Pankreas wird nach einer Übersicht der häufigsten Tumoren auf neue Entwicklungen der funktionellen Pankreasdiagnostik eingegangen. Abschließend werden die chronische Pankreatitis sowie die Autoimmunpankreatitis kurz im Spiegel der aktuellen Studienlage dargestellt.

Kernaussagen:

• Verschiedene Subtypen von Leberadenomen mit unterschiedlichen therapeutischen Konsequenzen können radiologisch MRT basiert differenziert werden.

• Extrazelluläres leberspezifisches Kontrastmittel sowie diffusionsgewichtete Bildgebung in der MRT der Leber sind stark befortschte radiologische Bildgebungsmethoden mit großem diagnostischen Potential.

• Bei Pankreasneoplasien sind funktionelle MRT Bildgebung mit Diffusion und Perfusion die aussichtsreichen neuen radiologischen Methoden.
