Feasibility of duplex TCD shown in healthy volunteers; hypothesis-generating for reproducibility gains, but should not yet change practice.
Observational (n=13)
Duplex transcranial Doppler allows for direct imaging and measurement of cerebral artery velocities, potentially improving reproducibility over traditional blind methods.
Hashimoto et al. (1991) conducted an observational in Healthy volunteers (n=13). Duplex transcranial Doppler examination was evaluated on Peak velocities and resistive indices on middle, anterior, and posterior cerebral arteries. Duplex transcranial Doppler examination successfully identified cerebral vessels and obtained peak velocities and resistive indices in 13 healthy volunteers.
