...José Manuel Valdueza; Olaf Hoffmann; Florian Doepp; Rudolf Lehmann; Karl Max Einhäupl The purpose of this report is to present normal values for venous blood flow velocities from the parasellar region using transcranial Doppler ultrasound (2-MHz transducer) with both transtemporal and transorbital...

...Bernhard Kleiser; Dieter Scholl; Bernhard Widder Transcranial Doppler sonography measures cerebrovascular reserve capacity by comparing blood flow velocities in basal cerebral arteries before and after vasostimulation by different methods. This presupposes constancy of the vessel diameter insonated...

...N.G. Wahlgren; G. Hellström; C. Lindquist; A. Rudehill The effect of electric stimulation of the sympathetic cord in the upper thoracic level on the middle cerebral artery blood flow velocity (V MCA ) in humans was examined using transcranial Doppler sonography monitoring during surgery for palmar...
