Magnetresonanzmikroskopie des Akkommodationsapparats

Zusammenfassung

Die Ultrahochfeld-Magnetresonanzmikroskopie (MRM) erlaubt die Akquisition von Magnetresonanzbildern (MR-Bildern) mit einer Auflösung im Submillimeterbereich. Damit ermöglicht sie eine weitestgehend artefaktfreie, untersucherunabhängige Darstellung der Strukturen und der Konfiguration des humanen Auges, die üblicherweise durch herkömmliche Visualisierungstechniken nicht erreicht werden kann. Der vorliegende Artikel korreliert die MRM des anterioren Augenabschnitts und des Akkommodationsapparats bei 9,4 Tesla mit der konventionellen Histologie.

Abstract

Magnetic resonance microscopy (MRM) at ultra-high magnetic fields allows acquisition of high resolution MR images in the micrometre range. The use of ultra-high magnetic fields opens the possibility of user-independent and artefact-free detailed characterisation of the anatomical tissue of the human eye, which is not achievable with classical imaging techniques. This article correlates MRM of the anterior eye segment and the accommodative apparatus at 9.4 Tesla with conventional histology.
