This results in a color assignment: red and blue indicate direction of flow with respect to the ultrasound beam, and lighter shades represent higher velocities. The carotid bifurcations of 10 normal subjects were studied. Changes in flow velocities across the arterial lumen were clearly visualized ...
Evaluation of cerebral AVM\"s using transcranial Doppler ultrasound Blood flow velocities in basal cerebral arteries were recorded noninvasively in 28 patients with cerebral (AVM's) and were correlated with the angiographic... KF Lindegaard,P Grolimund,R Aaslid,... - 《Journal of Neurosurgery》...
The Normal Examination Abstract Precordial, suprasternal and subcostal windows offer a multitude of views for the echocardiographic examination of the heart and great vessels in infancy and childhood. While two-dimensional echocardiography provides very good options for detailed morphologic cardiovascular asse...

Ultrasonic duplex scanning was used for flow velocity measurement in the extracranial carotid vessels in 92 presumably healthy volunteers aged 20–82 and in 14 patients aged 23–72 with normal carotid vessels on angiography. Velocities were examined as a function of age, diameter, blood pressure, ...
internal carotid arterypressor responseultrasound DopplerWe used a longitudinal study design (gestational weeks 8, 15, 22, 29, and 36 and 12 wk postpartum ) to investigate the effect of normal pregnancy on cerebral autoregulation and pressor response. Blood flow velocities in the right internal ...
Mental stress caused a significant increase in PW Doppler velocities in MCA from baseline in normal subjects, whereas no change occurred in hypertensive subjects despite a similar increase in heart rate and blood pressure in response to mental stress in both groups. Conclusion: Mental stress produces...
