Vector Velocity Imaging
Velocity vector imaging is a new quantitative echocardiographic modality. It is usually applied to grayscale echocardiographic images. Its potential for clinical use is its ability to quantify LV mechanical dyssnchrony and predict response to cardiac resynchronization therapy. Tissue velocities can be determined through automated tracking of B-mode image patterns from standard apical 2-chamber, 4-chamber, and long axis views.
This technique is angle independent and is able to provide an avenue for the evaluation of the short-axis mechanics of the LV.
