Prenatal Sonography in Hydranencephaly

ydranencephaly is a severe, sporadic brain abnormality characterized by absence of the cerebral hemispheres, which are replaced by a large supratentorial fluid-filled saclike structure surrounding the brain stem.1,2 This condition is thought to be the result of extensive brain necrosis secondary to a vascular insult involving the internal carotid arteries, which occurs after the brain and ventr...

Three-dimensional transcranial color-coded sonography of cerebral aneurysms.

BACKGROUND AND PURPOSE The role of 2-dimensional transcranial color-coded sonography (2D-TCCS) as a diagnostic tool in cases of vascular alteration is unquestioned. The skill of the operator, however, may be responsible for some intertrial variability. The clinical value of a new, workstation-based, 3D reconstruction system for TCCS was evaluated in patients with intracranial aneurysms. METHO...

Three-dimensional color Doppler sonography in carotid artery stenosis.

BACKGROUND AND PURPOSE Color Doppler sonography (CDS) suffers from such disadvantages as high interobserver variability and problems with data presentation and storage. We therefore performed a prospective trial to assess the role of three-dimensional CDS (3D-CDS) in the evaluation of internal carotid artery stenosis (ICAS). METHODS We included 32 consecutive patients with sonographically ver...
