Usefulness of transcranial color-coded sonography in the diagnosis of cerebral vasospasm.
BACKGROUND AND PURPOSE The noninvasive diagnosis of cerebral vasospasm with the use of conventional transcranial Doppler ultrasonography (TCD) is based on a velocity study of the middle cerebral artery (MCA). The authors report a prospective comparative study between transcranial color-coded sonography (TCCS), conventional transcranial Doppler (TCD), and angiography in the diagnosis of cerebral...
متن کاملTranscranial Color-Coded Sonography of the Basal Cerebral Circulation
Background and Purpose Transcranial color-coded sonography is a new development in noninvasive cerebral vascular imaging. Reference data using this technique are described. Methods Blood velocities and pulsatility and resistance indices were determined in the anterior cerebral, middle cerebral, posterior cerebral, vertebral, and basilar arteries in 115 volunteers after correction for the angle ...
متن کاملThree-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...
متن کاملTranscranial color-coded duplex sonography in cerebral aneurysms.
BACKGROUND AND PURPOSE Diagnosis and successful therapy before rupture of cerebral aneurysms would be most desirable in view of the high mortality and morbidity rates of aneurysmal subarachnoid hemorrhage. Using transcranial color-coded duplex sonography, we studied radiologically proven cerebral aneurysms to define ultrasonographic criteria and sensitivity for their diagnosis and detection. ...
متن کاملDiagnosis of middle cerebral artery occlusion with transcranial color-coded real-time sonography.
PURPOSE To determine the usefulness of transcranial color-coded real-time sonography in detecting occlusion of the horizontal portion of the middle cerebral artery. METHODS Using transcranial color-coded real-time sonography, we measured the end-diastolic flow velocity with incident angle correction and the side-to-side ratio of the end-diastolic flow velocity (the end-diastolic ratio) in bot...
