Abstract
Although ultrasound is the primary means of screening for fetal central nervous system (CNS) malformations, MRI has demonstrated added value in the evaluation of abnormalities not well assessed with sonography and in select circumstances for screening. In many fetal MRI practices, evaluation of the CNS is the most common indication for fetal MRI. MRI has demonstrated particular utility in evaluating the posterior fossa, midline structures, and cortex in the progressively ossifying fetal skull. The most common CNS indications are identified in Table 6.1 [98].
