Cerebral blood flow dynamics during pain processing investigated by functional transcranial Doppler sonography.
OBJECTIVE Functional transcranial Doppler sonography (fTCD) enables reliable quantification of cerebral blood flow modulation during neural activation processes. Its high-time resolution, relatively simple technical arrangement, and low costs could make fTCD a useful tool in the investigation of brain activity underlying pain experience in fundamental and clinical research. The present pilot st...
متن کاملInterhemispheric comparisons of cerebral blood flow velocity changes during mental tasks with transcranial Doppler sonography.
OBJECTIVE The purpose of this study was to evaluate hemispheric asymmetry of cerebral blood flow changes during various mental tests by applying transcranial Doppler sonography (TCD) to simultaneously monitor bilateral cerebral blood flow velocity changes. METHODS Twenty-one participants without cerebrovascular disease performed 3 left hemispheric tasks (reading, calculation, and color scalin...

15 صفحه اولTranscranial Doppler sonography monitors cerebral blood flow of mannitol-treated patients with acute large hemispheric infarction.
AIM To evaluate the effect of mannitol at different doses (125 ml and 250 ml) by transcranial Doppler (TCD) sonography in patients with acute large hemispheric infarction. MATERIAL AND METHODS 33 patients with acute large hemispheric infarction were enrolled, and the systolic peak velocity (Vs), end of diastolic velocity (Vd), mean velocity (Vm), pulsitility index (PI) and percentage rate (PR...
متن کاملTranscranial doppler sonography diagnostic value for the cerebral flow velocity changes in the interictal phase of classic migraine
Background: An imbalance of the cerebrovascular response during functional activation of the brain has been postulated as a factor in the pathophysiology of migraine. The purpose of this study was to determine the transcranial doppler sonography (TDS) diagnostic value for the cerebral flow velocity changes in the interictal phase of classic migraine. Methods: This study was carried out on 46 pa...
