Evaluation of Fetal Central Nervous System Abnormalities with Ultrafast MRI

Abstract

Central nervous system (CNS) abnormalities affect approximately 6000 neonates each year in the United States. The standard prenatal approach for evaluating these anomalies is ultrasonography (US). However, the sonographic evaluation of the fetal CNS is limited.

41 fetuses with suspected abnormal central nervous system (CNS) underwent prenatal MRI. In each case MR allowed for visualization of the region of suspected abnormality. MR added additional information to that provided by ultrasound in 28 cases.

When a CNS anomaly is detected by US, then MR may demonstrate additional findings which alter patient counseling and management.
