Transcranial Doppler ultrasound examination (TCD) images. Basilar artery flow is identified below medulla on a sagittal view of color flow Doppler (A). Measurement of basilar arterial flow by pulsed Doppler (B). Systolic mean velocity (Sm) and diastolic mean velocity (Dm) are discriminated by an end‐T wave of ECG.
