Transcranial Doppler (TCD) can monitor middle cerebral artery (MCA) velocity which can be
recorded simultaneously with other physiologic parameters such as end tidal (Et) CO 2 …

Sonographic findings in patients with superior sagittal sinus thrombosis were compared to
those in healthy adults. Two patients with angiographically venf1ed superior sagittal sinus …

Objectives To test the assumption that transcranial Doppler ultrasound (TCD) is able to
detect and to monitor intracranial venous blood flow velocities in patients with confirmed …

OBJECTIVE: An important limitation of transcranial Doppler (TCD) ultrasonography is its
inability to directly measure blood flow or vessel diameter. To extend the ability of TCD …

We have developed a method of non-invasively detecting language lateralisation by
measuring the increase in middle cerebral artery blood flow velocity occuring during a word …

A mathematical model of cerebral hemodynamics during vasospasm is presented. The
model divides arterial hemodynamics into two cerebral territories: with and without spasm. It …

The relationship between cerebral hemodynamics and cognitive performance has
increasingly become recognized as a major challenge in clinical practice for older adults …

Transcranial ultrasonography has become a valuable diagnostic tool for the bed-side
evaluation of cerebral hemodynamics. While the assessment of arterial blood flow is well …

Slow and rhythmic spontaneous oscillations of cerebral and peripheral blood flow occur
within frequencies of 0.5-3 min~ 1 (0.008-0.05 Hz, B-waves) and 3-9 min~ 1 (0.05-0.15 Hz …

PURPOSE To determine the ability of transtemporal power-and frequency-based
transcranial color-coded duplex sonography to aid in the assessment of cerebral veins and …
