High filter imaging of cardiac jets reduces variability: insights from computer modeling

摘要

Color Doppler flow mapping has become a widely used technique for detection of regurgitant flow through heart valves. While the technology allows for effective detection of these lesions, quantification of their severity by color Doppler has not been achieved in the clinical setting. This study addressed the hypothesis that elevation of wall filters beyond the levels needed to eliminate structure noise can produce more stable images of jets in the face of previously demonstrated causes of variability.
