Key result
Doppler right internal carotid end-diastolic velocity strongly correlates with right hemispheric blood flow.
Why the study?
Does Doppler carotid velocity measurement accurately predict hemispheric blood flow measured by 133Xe inhalation in patients without arterial pathology?
Observational (n=30)

Effect estimate: r = 0.88
p-value: p=< 0.001
Doppler internal carotid end-diastolic velocity provides a fairly accurate prediction of hemispheric blood flow in patients without arterial abnormalities.

Supports Doppler end-diastolic velocity for estimating hemispheric flow without carotid disease; leaves open validation in atherosclerotic cohorts.
Risberg et al. (1980) conducted an observational in Psychiatric disorders without arterial pathology (n=30). Doppler carotid velocity measurements vs. 133Xe inhalation method was evaluated on Correlation between right hemispheric blood flow and right internal carotid end-diastolic velocity (r = 0.88, p=< 0.001). Doppler right internal carotid end-diastolic velocity strongly correlated with right hemispheric blood flow measured by 133Xe inhalation (r = 0.88, p < 0.001).
