Frontal 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 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 کاملTranscranial color duplex sonography in childhood and adolescence. Age dependence of flow velocities and waveform parameters.
BACKGROUND AND PURPOSE Transcranial color duplex sonographic examinations in children and adolescents without cerebrovascular disease were evaluated retrospectively. Flow velocities and waveform parameters were determined and their side-to-side differences and age dependence analyzed and, finally, compared with analogous data of a previously described group of healthy adults. METHODS With a 2...
متن کاملDifferentiation between intracerebral hemorrhage and ischemic stroke by transcranial color-coded duplex-sonography.
BACKGROUND AND PURPOSE The differential diagnosis of intracerebral hemorrhage versus ischemic stroke has critical implications for stroke management. Transcranial color-coded duplex sonography (TCCS) has been shown to identify intracerebral hemorrhages and intracerebral vessel occlusions. We conducted this study to evaluate the sensitivity and specificity of TCCS in this differential diagnosis ...
