Flow Imaging in Clinical Practice Doppler
Color Flow Imaging
In Figure 4.1 there is a mitral regurgitant jet into the left atrium in systole and the regurgitant blood flow is displayed on the two-dimensional echocardiographic image. In color flow imaging, the colors red and blue represent direction of a given jet; the various hues from dull to bright represent the differing velocities. When turbulence is present, a mosaic of many colors results. A two-dimensional display of flow is, therefore, produced with ready identification of size, direction, and velocity.
