FIG 1. Schema shows relationship between transducer and vascular anatomy. The transducer was placed between the squama occipitalis and the palpable spinous process of the first cervical vertebra. After detecting blood flow signals from the VA, bilateral PICAs, and the BA by 2D power-Doppler imaging, the transducer was locked back and tilted very slowly to assess these arteries. Subsequently, by using a 3D digital system, 3D power-Doppler images of the vertebrobasilar arteries were reconstructed after rendering
FIG 2. 2D and 3D power-Doppler images.
A, 2D power-Doppler image shows the right VA (segments V3–V4), part of the PICA, and the left VA.
B, 3D power-Doppler study clearly depicts the Vas and the PICA branching from the right VA (arrow).
