Abstract Objectives To evaluate whether fetal brain magnetic resonance imaging (MRI) adds useful clinical information to that obtained by dedicated neurosonography using a combined transabdominal and transvaginal approach in fetuses with suspected anomalies. Methods In the 2‐year period between January 2000 2002, 42 underwent neurosonographic MRI examinations of brain. The referral indications were: asymmetric ventriculomegaly (13), (7), periventricular cysts (2), midline findings agenesis corpus callosum (3), infratentorial pathology cytomegalovirus (CMV) infection (2) miscellaneous (5). Results Neurosonography produced similar diagnoses 29 fetuses: normal examination (10), isolated (11), (1), pericallosal lipoma (1) cerebellar hemorrhage (1). were more accurate seven patients: hemimegalencephaly, lipoma, signs CMV infection, anomalies associated three ultrasound scan which suggested parenchymal abnormality. provided diagnosis third ventricular dilatation was ruled out, ventricles fetus an ultrasonographic finding ventricles, progression ventriculomegaly. patients identified pathologies differently interpreted, each another aspect anomaly or definitive not possible. Conclusions Our study demonstrated is equal most cases confirmed diagnosis; minority modality additional/different information. major role reassurance parents regarding presence absence Copyright © 2004 ISUOG.
