Zusammenfassung

Indikationen zur Durchführung einer fetalen Magnetresonanztomographie (MRT) setzen sich aus allgemeinen Fragestellungen zusammen, die auf methodischen Problemen von Ultraschalluntersuchungen (US) beruhen (wie beispielsweise Anhydramnion), und speziellen, bei denen die MR-Eigenschaften der hochauflösenden Gewebedifferenzierung und eines Untersuchungsfensters, das eine Abbildung des gesamten Fetus auch im fortgeschrittenen Schwangerschaftsalter erlaubt, ausgenützt werden. Im Vordergrund stehen dabei die Absicherung von US-Befunden, die Abklärung von Fehlbildungen in Hinblick auf individuelle Prognose und Vorliegen eines Syndroms mit genetisch determiniertem Hintergrund, und die Differenzierung erworbener Störungen von Fehlbildungen, die Abklärung von Veränderungen, die einer unmittelbar postnatalen operativen Therapie bedürfen, und morphologischer Veränderungen der Plazenta.

Abstract

Indications to perform fetal magnetic resonance imaging (MRI) are composed of common ones related to methodological problems of ultrasound (US) assessment (such as for instance hydramnios) and special ones. The latter are related to MR capability of high-resolution soft tissue contrast and an extended field of view that allows visualization of the whole fetus, even in later stages of pregnancy. The most important indications include confirmation of US findings, work-up of malformations with respect to individual prognosis and genetic background, differentiation between acquired conditions and malformations, visualization of pathologies that have to be treated surgically immediately after birth, and morphological changes of the placenta.
