Quantitative Evaluation of Flow Motion

Analysis of cardiac function with dynamic imaging techniques is not limited to the evaluation of cardiac motion, and some dynamic imaging techniques provide means to measure and evaluate the kinetic patterns of blood flow through the ventricular cavities and the large vessels. The measurement of flow velocity and identification of abnormal flow patterns allow better evaluation of the severity of valvular diseases, the presence of abnormal shunts, the alterations and dissections of vascular walls, and the hemodynamic anomalies in deficiencies of the cardiac function. Measures of flow velocity can be obtained from echocardiography studies using Doppler ultra-sonography techniques and from cine-MRI using phase encoding imaging techniques.
