OBJECTIVES: Magnetic resonance imaging (MRI) imaging can be useful when fetal central nervous system (CNS) anomalies are detected by ultrasound (USG). This study aims to compare the findings from USG and MRI with post-natal results in cases of fetal CNS anomalies.
MATERIAL AND: METHODS: This is a retrospective/prospective study that analyzed the records of 55 pregnant women who underwent both fetal MRI and USG and whose birth results were obtained due to suspected CNS abnormalities between 2020 and 2023.
RESULTS: Pearson correlation analysis and Blant-Altman analysis showed that USG and MRI results of right lateral ventricle measurement were more similar compared to left lateral ventricle measurement. When the cut-off value for lateral ventricle measurement was 10 mm, there was a difference in the USG and MRI results of only 1 pregnant woman in the right lateral ventricle USG-MRI comparison, whereas no difference was observed in 9 pregnant women in the left lateral ventricle analysis. One pregnant woman with healthy USG results was found to have corpus callosum hypoplasia by MRI and one pregnant woman with posterior fossa anomaly by USG had healthy MRI results. All other measurements showed similar results between USG and MRI.
CONCLUSIONS: Fetal MRI, when performed with appropriate indications in selected cases evaluated by USG, is useful for measuring the lateral ventricles and detecting various CNS anomalies. The advancing technology of USG and MRI devices, along with the experience of the physicians interpreting these examinations, will always be important.
