[MRI and fetal multidetector CT in the diagnosis of fetal malformations].
Prenatal imaging has benefitted from rapid technological progress in the last ten years. Ultrasound remains the standard screening method for fetal malformations but can be hindered by the bony structure of the skull. In particular, it can be difficult to distinguish between white and grey matter. MRI is a useful complementary method for detecting brain malformations. In particular, MRI is necessary to detect associated malformations and to obtain a precise diagnosis when ultrasound examination shows ventricular dilation. MRI is taking an increasingly important place in the assessment and prognostication of extracranial malformations such as congenital diaphagmatic hernia. We reviewed 2885 fetal MRI examinations. Fetal computed tomography is gradually replacing plain maternal abdominal radiography. We examined 90 CT films for fetal bone malformations.
