title: Congenital and perinatal lesions.
abstract: Most congenital abnormalities can be traced to defects occurring at a specific stage during embryologic development. Anatomic deformities of the ventricular system and brain surface are visualized and myelination of the white matter is well evaluated on MR scans so that congenital abnormalities may be differentiated from perinatal lesions. MR imaging is often the only imaging modality required for complete assessment of abnormalities in the neonatal period.
