Brain abnormalities in fetuses: in-utero MRI versus ultrasound
Feb 4, 2017 · Fetuses with identified intracranial abnormalities on ultrasound underwent iuMRI, mostly within 2 weeks of the ultrasound scan. An interesting component of the design is that radiologists doing iuMRI were not masked to the ultrasound diagnosis.
Essential elements surveyed in the head and neck include the lateral cerebral ventricles, choroid plexus, midline falx, cavum septi pellucidi, cerebellum, cisterna magna, upper lip, and nuchal fold. CNS abnormalities can be or-ganized into six main categories at prenatal US.
Ultrasonographic evaluation of the fetal central nervous system: …
The evaluation and diagnosis of CNS malformations during the prenatal period can be performed by ultrasound at any gestational age. The ultrasonographic evaluation includes the study of the brain and spinal cord.
Sonographic examination of the fetal central nervous system: guidelines ...
