Computerized detection of cerebral emboli and discrimination from artifact using Doppler ultrasound.

BACKGROUND AND PURPOSE Transcranial Doppler ultrasound can detect circulating cerebral emboli. Monitoring of patients with potential embolic sources may allow identification of high-risk patients who can then be selected for prophylactic treatment. However, practical patient monitoring will require automated programs that can detect emboli and differentiate them from artifact. METHODS A new o...

Transcranial Doppler Detection of Circulating Cerebral Emboli

Background: The identification of gaseous emboli using Doppler ultrasound was described as early as the 1960s. Recently it has been demonstrated that this method can also detect solid emboli such as thrombi and platelet aggregates. This may make this technology useful in a large number of patients with, or at risk of, embolic stroke. Summary of Review: Emboli appear as short-duration, high-inte...

Detection of arterial emboli using Doppler ultrasound in rabbits.

The purpose of this study was to develop an animal model that could be used to test the ability of Doppler ultrasound to detect arterial emboli composed of materials that are often involved in cerebral emboli. Emboli introduced into the rabbit aorta via the left renal artery consisted of clotted whole blood, platelets, atheromatous material, fat, or air. The ultrasound examination was carried o...
