Cerebral Blood Flow Velocity Using Doppler Techniques
Doppler ultrasound methods are increasingly used in the diagnosis of cervical and intracranial artery diseases. A combination of B-mode can detect the presence and quantify the severity of disease in common and internal carotid, subclavian and vertebral arteries in the neck. Aaslid et al.  in 1982 demonstrated that intracranial vessels can be insonated with ultrasound waves through the adult intact skull. In experimented hands, this non-invasive technique is fast, easy, accurate and reproducible, allowing to repeat the measurements as often as desired . Moreover, lightweight and portable equipment facilitates its use in the bedside assessment and monitoring of critically ill patients.
