4. 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 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.).

First 24 hr transcranial Doppler results in a 4-year-old girl admitted to hospital for a severe traumatic brain injury. L-MCA = Left middle cerebral artery; PI = pulsatility index; BA = basilar artery; R-MCA = right middle cerebral artery; L-EX-ICA = left extracranial internal carotid artery; R-EX-ICA = right extracranial internal carotid artery (For interpretation of the references to color in this figure, the reader is referred to the web version of this article.).

First 24 hr transcranial Doppler results in a 15-year-old boy admitted to hospital for a severe traumatic brain injury. L-MCA = Left middle cerebral artery; PI = pulsatility index; BA = basilar artery; R-MCA = right middle cerebral artery; L-EX-ICA = left extracranial internal carotid artery; R-EX-ICA = right extracranial internal carotid artery (For interpretation of the references to color in this figure, the reader is referred to the web version of this article.).
