Color bruit artifact
Citation, DOI and article data
The color bruit or tissue vibration artifact is a type of color Doppler ultrasound artifact which results in color signal overflowing to the perivascular tissues most often caused by stenosis, AV fistulas, or shunts. Thus, this artifact is useful by pinpointing areas of potentially pathological blood flow.
Turbulent flow causes vibration of the vessel wall and perivascular soft tissues, resulting in a detectable Doppler shift, which typically results in a mixture of red and blue speckles 2.
The color bruit is a beneficial artifact that helps with localizing areas of critical stenosis or turbulent flow due to other reasons 1,2.
