Effect of Contrast Agents on Results of Doppler Ultrasound Measurement of Blood Flow Velocity

A model describing the occurrence of methodological error in Doppler ultrasound measurement of blood flow velocity using contrast agents is suggested. The methodological error is due to the radiation pressure force. The influence of the contrast agent, the ultrasound parameters, and the vessel type...

Description
Summary:A model describing the occurrence of methodological error in Doppler ultrasound measurement of blood flow velocity using contrast agents is suggested. The methodological error is due to the radiation pressure force. The influence of the contrast agent, the ultrasound parameters, and the vessel type on the magnitude of the methodological error in the blood flow velocity measurement was studied.
