Using of magnetic resonance imaging and ultrasonography in neural migration defect detection .

The process called neural migration, which results in the formation of a cortical layer, occurs between the 3rd and 6th months, and if this process can not proceed in a healthy way, a neural migration defect occurs. With ultrasonography and magnetic resonance imaging, the detection of this condition and additional anomalies is increasing day by day. Imaging methods of fetal brain structures and neural migration defect findings were discussed in the literature. Ultrasonography and Magnetic Resonance Imaging can give information about many anomalies of the fetus nowadays. It is very useful in showing fetal brain anomalies especially when applied in major weeks
