Abstract :Monitoring fetal brain development is of great importance for the early diagnosis and management of anomalies. Magnetic Resonance Imaging, which is used for this purpose, allows for detailed morphometric analyses of structures such as the cerebral hemispheres and the ventricular system. For this purpose, it was planned to evaluate the development of the brain hemispheres and lateral ventricles throughout the fetal period and to obtain morphometric data. The study was conducted on 120 deceased human fetuses (63 males, 57 females) with gestational ages ranging from 12 to 40 weeks, who had no external pathology or anomalies. Initially, general external parameters were measured to determine the age of the fetuses. Then, using Magnetic Resonance Imaging, images of the cranial region were obtained in sagittal, axial, and coronal planes. From these images, two-dimensional parameters of the brain hemispheres and lateral ventricles, as well as volumetric parameters of the brain hemispheres, were evaluated. The mean and standard deviations of the obtained parameters were determined according to gestational weeks and trimester groups. There was no statistically significant difference in any of the parameters between the right and left sides or between genders (p>0.05). A positive correlation was found between all the obtained parameters and gestational age. We believe that the data obtained throughout the study will be helpful in evaluating the development of the cerebral hemispheres and lateral ventricles in disciplines such as obstetrics, perinatology, and pediatrics, in earlier detection of regional anomalies, and in determining treatment possibilities.
