Visualization of the basilar artery by transcranial color-coded duplex sonography : comparison with postmortem results.
BACKGROUND AND PURPOSE Transcranial color-coded sonography (TCCS) via the suboccipital approach allows direct and continuous visualization of the basilar artery (BA). In this study, we intended to evaluate the ability of native TCCS in visualizing the length of the BA by means of a comparison with postmortem measurements. METHODS The BA was prospectively studied by TCCS shortly before death (...
متن کاملTranscranial color-coded duplex sonography of intracerebral hematomas in adults.
BACKGROUND AND PURPOSE It is well established from pediatric experience and animal experiments that intracerebral blood can be demonstrated by B-mode real-time duplex scanning. This has recently become feasible in adults as well. The present study investigated the changes in the sonographic appearance of intracerebral hematomas over the course of time. METHODS Starting in May 1991, 23 consecu...
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 کاملFrontal bone windows for transcranial color-coded duplex sonography.
BACKGROUND AND PURPOSE The use of the conventional temporal bone window for transcranial color-coded duplex sonography (TCCS) often results in difficulties in obtaining angle-corrected flow velocity measurements of the A2 segment of the anterior cerebral artery, the posterior communicating artery, and the midline venous vasculature because of the unfavorable insonation angle. The same applies t...
متن کاملTranscranial color-coded duplex sonography for detection of distal internal carotid artery stenosis.
BACKGROUND AND PURPOSE Gradation of high-grade intracranial internal carotid artery (ICA) stenosis poses a challenge to noninvasive neurovascular imaging, which seems critical for angioplasty in the ICA segments C1 and C5. We investigated cutoff values of intracranial ICA stenosis for transcranial color-coded sonography (TCCS) and compared this method with the "gold standard," digital subtracti...
