title: Special Doppler ultrasound transducers for recording vertebral artery blood flow in rabbits.
abstract: Two kinds of transducers and a surgical procedure by means of which the vertebral artery of rabbits can be insonated through the acoustic window between atlas and axis are presented. A range-gated pulsed Doppler ultrasonic device of 10 MHz is used. Rabbit vertebral Doppler waveforms are characterized by high end-diastolic flow and a modified Pourcelot Index of 0.3. They are identical to those recorded from human vertebral arteries.
