RECIO RODRIGUEZ, Manuel et al. Abnormalities in fetal CNS: Interesting issues to the obstetrician. Rev. argent. radiol. [online]. 2010, vol.74, n.4, pp.385-396. ISSN 1852-9992.

Fetal MR imaging (MRI) is an increasingly available technique used to evaluate the fetal brain and spine, because it provides a unique opportunity to evaluate fetal brain development and to make an early diagnosis of congenital abnormalities. MRI allows a better differentiation between normal and abnormal signal intensity of fetal tissues due to its higher contrast resolution compared to prenatal sonography (US). Therefore, structural abnormalities such as brain malformations and destructive lesions that could be sonographically occult on prenatal sonography can be detected at fetal MRI. We review indications, utility, safety, and technical aspects of fetal MR imaging and the appearance of normal fetal brain development evaluating its contribution in the diagnosis of fetal diseases of different brain regions and spinal disorders.
