MRI Versus Four Dimensional Ultrasound in Detection of CNS Fetal Congenital Anomalies

Congenital central nervous system (CNS) anomalies are common and most devastating. They occur in frequency of about 1.4 to 1.6 per 1000 live births but are seen in about 3-6% of still births.They account for 40% of deaths of all infants in the first year of life. In survivors, they cause a variety of neurological disorders, mental retardation or drug resistant epilepsy. CNS anomalies are usually compatible with life, prolonged hospitalization, higher health care costs, uncertain future life quality and significant burden to families and society.
