Abstract.
Diagnosis of congenital anomalies during pregnancy is a challenge, which has been solved mainly using ultrasound imaging methods.
Results. While analyzing the examination results of 30 pregnant women with the fetus congenital malformations, with the exception of the group of the brain and spine malformations, the diagnostic accuracy of the isolated use of the ultrasound imaging method for the specified anomalies was 78% with 76% sensitivity. The diagnostic accuracy of the isolated use of MRI was 97% with approximately 96% sensitivity. At the same time, the diagnostic accuracy when using the combination of ultrasound and MRI was 100%, the sensitivity at the validation stage was 98%.
Conclusions. Fetal MRI increases diagnostic options in assessing developmental defects, exept for the group of congenital malformations of the brain and spine. MRI allows obtaining a high-quality image of the fetal structures in cases where such an image cannot be obtained during ultrasound examination due to artifacts. The MRI method is characterized by comparative superiority over ultrasound in the differential diagnosis of congenital malformations, being a means of obtaining additional diagnostically significant information. The results obtained during the use of fetal MRI often serve as the basis for changing the initial prenatal diagnosis of congenital malformations detected with ultrasound.
