MRI DIAGNOSTICS OF CORTICAL DEVELOPMENT MALFORMATIONS, FETUS BRAIN DIVERTICULATION ANOMALIES

Abstract

Materials for fetus brain state evaluation by means of magnetic resonance image (MRI) have been presented. Indication for MRI — changes detected or suspected in the course of fetus ultrasound examination (USE), compromised anamnestic record, difficulties of US examination performance. MRI overcomes USE in cortical development anomalies diagnostics, posterior cranial fossa anomalies diagnostics, fetus brain destructive damages diagnostics. Major diagnostics challenges are associated with cortical development malformations detections, which may further cause neurological deficiency, developmental legging. MRI allows evaluation of culci cerebri condition, which is vitally important for lissencephaly and polymicrogyria diagnostics; determination of ventricular system condition, which is subject to changes under septooptic dysplasia, holoprosencephaly, schizencephaly; detection of brain parenchyma changes under heterotopia. Successful diagnostics of cortical dysplasia depends on the equipment, correct choice of radio-frequency coil and scanning protocol, which are optimal for the given gestation term and anomaly type.
