Use of a decibel threshold in detecting Doppler embolic signals.

Abstract

BACKGROUND AND PURPOSE To improve reproducibility and reliability in the identification of embolic signals detected with the use of Doppler ultrasound, many studies have used an intensity threshold. However, variable thresholds between 3 and 12 dB have been used, and often the method of measurement of intensity is not stated. Potentially different methods… (More)
