Zusammenfassung

Seit Einführung der fetalen Magnetresonanztomographie (MRT) in die pränatale Diagnostik wurde das Verfahren durch neue Spulentechniken und die Entwicklung ultraschneller Sequenzen kontinuierlich weiter entwickelt. Gegenwärtig steht eine Vielzahl von Sequenzen zur Verfügung, die es erlauben, mit hoher Bildqualität und räumlicher Auflösung selbst in fortgeschrittenen Schwangerschaftsstadien den gesamten Feten darzustellen. Unter Berücksichtigung der speziellen Untersuchungsbedingungen und des Schwangerschaftsalters kann so die fetale Anatomie genau abgebildet werden. Die Vielfalt an Sequenzen und deren gezielter Einsatz ermöglichen es weiter, fetale Gewebe und Pathologien näher zu charakterisierten. Auf diese Weise liefert die fetale MRT nicht nur Zusatzinformationen zur Routineultraschalluntersuchung, sie gibt auch Aufschluss über bestimmte fetale Morphologien und Pathologien, die bisher nicht darstellbar waren.

Abstract

Since the introduction of fetal magnetic resonance imaging (MRI) into prenatal diagnostics, advances in coil technology and development of ultrafast sequences have further enhanced this technique. At present numerous sequences are available to visualize the whole fetus with high resolution and image quality, even in late stages of pregnancy. Taking into consideration the special circumstances of examination and adjusting sequence parameters to gestational age, fetal anatomy can be accurately depicted. The variety of sequences also allows further characterization of fetal tissues and pathologies. Fetal MRI not only supplies additional information to routine ultrasound studies, but also reveals fetal morphology and pathology in a way hitherto not possible.
