The MR appearance of CSF flow in patients with ventriculomegaly.
The purpose of this study was to investigate the MR imaging appearance of mobile CSF in the ventricular system in patients with ventriculomegaly caused by brain atrophy and extraventricular obstructive hydrocephalus. Pulsatile CSF often has decreased intensity relative to less mobile areas of CSF, particularly on T2-weighted scans. At times, the flow-related signal dropout causes striking heter...
متن کاملCortical maturation in fetuses referred for 'isolated' mild ventriculomegaly: a longitudinal ultrasound assessment.
OBJECTIVES To compare cortical maturation between fetuses with isolated mild ventriculomegaly (IMV) and healthy fetuses, and to explore its potential prognostic value in IMV. METHODS This prospective study quantified cortical maturation by ultrasound in 24 fetuses with IMV and 46 healthy fetuses. Depth and grading the developmental pattern of the parieto-occipital fissure (POF), calcarine fis...
متن کاملCortical overgrowth in fetuses with isolated ventriculomegaly.
Mild cerebral ventricular enlargement is associated with schizophrenia, autism, epilepsy, and attention-deficit/hyperactivity disorder. Fetal ventriculomegaly is the most common central nervous system (CNS) abnormality affecting 1% of fetuses and is associated with cognitive, language, and behavioral impairments in childhood. Neurodevelopmental outcome is partially predictable by the 2-dimensio...
متن کاملMR elastography and MRI volumetry of the aging brain
Background: Physiological aging of the brain is accompanied by ubiquitous degeneration of neurons and oligodendrocytes [1]. An alteration of the cellular matrix of an organ impacts its macroscopic viscoelastic properties, which are characterized by mechanical parameters such as stiffness and internal friction. To date Magnetic Resonance Elastography (MRE) is the only non-invasive technique for ...
متن کاملFetal Ventriculomegaly: Investigating Additional Brain Abnormalities by using MR Imaging
Background and Purpose: Fetal ventriculomegaly (VM), is known to have a prevalence of association with other brain abnormalities. By using in utero MR imaging (iuMR), we aimed to determine the prevalence of brain abnormalities other than VM and investigate the hypothesis that the prevalence of having additional brain abnormalities (ABA) increases with the degree of VM. Materials and Methods: We...
