Transcranial Doppler ultrasonography to evaluate cerebral hemodynamic changes in neurocysticercosis

Arquivos de Neuro-Psiquiatria
Background Arteritis is a complication of neurocysticercosis (NCC), which is not well known and could trigger strokes. The transcranial Doppler ultrasound (TCD) is a noninvasive method for detecting, staging, and monitoring cerebrovascular ...

Transcranial duplex doppler ultrasonography in dogs with hydrocephalus Ultrassonografia duplex Doppler transcraniana em cães com hidrocefalia

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2010
Transcranial duplex Doppler ultrasound was performed in 32 conscious dogs presenting ventriculomegaly detected in B-mode, obtaining measures of lateral ventricles and resistance parameters of main cerebral arteries before and after 30 days of clinical ...

Sex differences in cerebral blood flow and cardiac function in response to exercise in the heat

Experimental Physiology, EarlyView.
Abstract We investigated the effect of exercising in hot conditions on cerebral blood flow and systolic left ventricular (LV) function in males and females, to explore sex differences. The experimental condition consisted of walking on a treadmill at 5 km/h and 2% incline, inside a heat chamber at 40°C (50% relative humidity), for 90 min.

The effect of combined treatment with transcranial direct current stimulation on cerebral blood flow in patients with cerebral palsy

Zaporožskij Medicinskij Žurnal, 2017
There is a close link between the activity of the brain and cerebral blood supply. Transcranial direct current stimulation (tDCS) modulates the activity of the cerebral cortex and thus affects the cerebral blood flow.

Cerebrovascular flow‐mediated dilation in humans: Methodological challenges, physiological interpretation and future integrations

Experimental Physiology, EarlyView.
Abstract Arterial shear‐mediated vasodilation is a well‐established measure of endothelial function and serves as a critical biomarker for cardiovascular disease risk. Endothelial function can be measured using a variety of experimental methodologies; however, the most widely adopted technique is ultrasound‐based flow‐mediated dilation (FMD), in which ...

Doppler ultrasonography of the lower extremity arteries: Anatomy and scanning guidelines

, 2018
Doppler ultrasonography of the lower extremity arteries is a valuable technique, although it is less frequently indicated for peripheral arterial disease than for deep vein thrombosis or varicose veins.

Transcranial sonography in Parkinson’s disease [PDF]

Einstein (São Paulo), 2012
Transcranial sonography has become a useful tool in the differentialdiagnosis of parkinsonian syndromes. This is a non-invasive, low costprocedure. The main finding on transcranial sonography in patientswith idiopathic Parkinson’s disease is an increased

Whole‐body hot water immersion effect on cerebral haemodynamics and subsequent cerebrovascular reactivity to carbon dioxide

Experimental Physiology, EarlyView.
Abstract To test the hypothesis that hot water immersion (HWI) improves cerebrovascular function via shear‐mediated mechanisms, this study determined cerebrovascular reactivity to carbon dioxide (CVRCO2${\mathrm{CV}}{{\mathrm{R}}_{{\mathrm{C}}{{\mathrm{O}}_2}}}$) before and after 60 min of 39°C HWI and a 21°C air control (CON) in 15 healthy ...

Role of transcranial Doppler ultrasonography in acute stroke

Annals of Indian Academy of Neurology, 2008
Background: Transcranial Doppler (TCD) ultrasonography is the only noninvasive examination that provides a reliable evaluation of intracranial blood flow patterns in real-time, adding physiological information to the anatomical information obtained from

Transcranial sonography: practical use in the intensive care unit

Anaesthesiology Intensive Therapy
Brain ultrasonography has emerged as a valuable diagnostic and monitoring tool in intensive care, complementing other point-of-care techniques. Transcranial colour-coded duplex (TCCD) offers a rapid, non-invasive, repeatable, and cost-effective bedside ...
