Objective Evaluation of Sylvian Fissure Development by Multiplanar 3-dimensional Ultrasonography

摘要

ObjectiveEvaluation of fetal cerebral cortex sulcation is important for the prenatal diagnosis of neuronal migration disorders. Although abnormal sylvian fissure morphological features are frequently observed in these conditions, the diagnosis of an abnormal sylvian fissure relies on subjective interpretation of ultrasonographic images. This study was performed to develop an objective ultrasonographic parameter for sylvian fissure evaluation.
