Key result
Elevation of wall filters beyond levels needed to eliminate structure noise can produce more stable images of cardiac jets in computer modeling.
Why the study?
Does high filter imaging reduce variability in color Doppler flow mapping of cardiac jets in computer models?
Does high filter imaging reduce variability in color Doppler flow mapping of cardiac jets in computer models?
Computer modeling suggests that elevating wall filters in color Doppler flow mapping can reduce variability and produce more stable images of cardiac jets.
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.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Cape et al. (2002) studied Regurgitant flow through heart valves. Elevation of wall filters vs. Standard wall filters was evaluated on Stability of images of jets. Elevation of wall filters beyond levels needed to eliminate structure noise can produce more stable images of cardiac jets in computer modeling.
