Role of magnetic resonance imaging in fetuses with mild or moderate ventriculomegaly in the era of fetal neurosonography: systematic review and meta-analysis
OBJECTIVES:
To report the rate of additional anomalies detected exclusively on prenatal MRI in fetuses affected by isolated mild or moderate ventriculomegaly (VM) according to the type of ultrasound protocol adopted (dedicated neurosonography vs standard assessment of fetal brain) and to explore whether the diagnostic performance of fetal MRI in detecting such anomalies is affected by gestational age at scan and laterality of ventricular dilatation.
