In this study, an ultrasonographic ventriculumegaly (VM) and ventricular system-related anomalies (VSIA) can be identified or suspected for ethological assessment and distinctive diagnosis, in order to identify other accompanying anomalies of the central nervous system (SSS) or to investigate the role of fetal magnetic resonance imaging (MRG) in cases where the ultrasonography (US) examination remains insufficient. Between June 2008 and January 2011, obstetric ultrasound with fetal VM and VSA or 80 pregnancies (80 fetus) with suspicious fetal MRG tests were evaluated as retrospective. The age of the study women varies between 17 and 45 years (an average of 27 years). The period of pregnancy determined by the date of the last menstruation is between 18-35 gestational weeks (medium 25 weeks). In our study, fetal MRG; isole VM (n=39), combined VM (n=6), mega sisterna magna (n=11), colposphaly, corpus kallosum agenesis suspicion (n=9), Dandy Walker malformation/variant (n=9), 4.ventricle dilatation (n=2), 3.ventricle dilatation (n=3), monoventricle, holoprozensefali (n=3), meningomyelosel (n=2) indications were applied. Furthermore, a fetal MRG examination was carried out in three patients due to the lack of U.S. assessment related to morbid obesity and the failure to assess lateral ventricles in one patient as U.S. and was included in the study in terms of showing U.S. limits. Fetal MRG has resulted in a change in the diagnosis in 23 cases (28.75) and in 28 cases (35%) has confirmed additional findings. In 29 of the cases (36.25%) MRG confirmed the pre-diagnosis placed with the US, did not detect any additional anomaly but provided more anatomical details. Fetal MRG, with high contrast resolution, can provide more specific information about normal development in the fetal brain assessment, as well as fetal ventriculomegaly and VSIA in the presence can provide much more anatomical details and information than the US, can make significant contributions to the direction of pregnancies.
