Der Hippokampus

Zusammenfassung

Die paarige Struktur Hippokampus ist für das Gedächtnis und im weiteren Sinne für das „Menschsein” von elementarer Bedeutung, seine In-vivo-Untersuchung erfolgt heute mit einer hochaufgelösten, „anatomisch orientierten” MR-Tomographie. Wichtigste Sequenzen sind koronare, 2 oder 3 mm dicke T2w oder FLAIR-TSE-Aufnahmen, die senkrecht zur Längsachse des Hippokampus verlaufen. In dieser Übersichtsarbeit werden diagnostische „pitfalls” und Befunde bei den häufigsten Hippokampuserkrankungen dargestellt.

Abstract

The twin structure of the hippocampus is a vital importance for memory and “human being”, it is in vivo examined by anatomically oriented, high-resolution MRI. Important MR sequences are coronal, 2 or 3 mm thick, T2-weighted or Flair fast spin echo sequences which are set at an angle perpendicular to the length axis of the hippocampus. This review article focuses on diagnostic pitfalls and illustrates MR imaging findings of the most common diseases.
