Changes in Middle Cerebral Artery Blood Flow Velocity During Sonolysis Using a Diagnostic Transcranial Probe With a 2-MHz Doppler Frequency in Healthy Volunteers

摘要

Ultrasound has various biological effects in the human body. The effects of continuous monitoring with ultrasound (sonolysis) on vasodilatation of the radial artery were described recently. We wanted to ascertain whether similar changes in the blood flow velocity during sonolysis could also be detected in the middle cerebral artery.
