The effect of receiving chamber environment on the visualization of cardiac jets by color Doppler flow mapping

Jet spatial resolution as visualized by color Doppler flow mapping has previously been shown to be affected by physical factors, such as driving pressure, and technical factors, such as instrument settings. An additional factor producing superimposed variability, namely, the interaction of the jet w...

Zusammenfassung:Jet spatial resolution as visualized by color Doppler flow mapping has previously been shown to be affected by physical factors, such as driving pressure, and technical factors, such as instrument settings. An additional factor producing superimposed variability, namely, the interaction of the jet with solid boundaries, in the distal receiving chamber, is illustrated. The broader point that jet velocities (i.e., Doppler images) do not uniquely represent jet volume is demonstrated.< >
