How accurately does current fetal imaging identify posterior fossa anomalies?

Objective: The first objective of our study was to describe the prevalence and spectrum of posterior fossa anomalies over 5 years in a major fetal care center where the referral diagnosis (by fetal sonography) was investigated by fetal MRI and, if confirmed, by postnatal MRI if possible. The second objective was to assess the accuracy with which fetal MRI predicts postnatal MRI findings in this population.

Materials And Methods: We retrospectively identified all cases of suspected fetal posterior fossa anomalies referred to our center from 2002 through 2006.
