Figure 3 Example of mean flow velocities of the L-MCA, BA, and R-MCA. The color Doppler flow tracings demonstrate an L-MCA at a velocity of 87.0 cm/s at a depth of 50 mm and a PI of 1.50, BA velocity of 51.2 cm/s at a depth of 70 mm with a PI of 1.29, and an R-MCA velocity of 92.4 cm/s at a depth of 50 mm with a PI of 1.13. L-MCA = Left middle cerebral artery; R-MCA = right middle cerebral artery; BA = basilar artery; PI = pulsatility index (For interpretation of the references to color in this figure, the reader is referred to the web version of this article.).
