AB Multigated cardiac studies were computer processed to produce cine mode images of change in volume with change in time, dv/dt. In a twenty frame gated blood pool study, both positive and negative volume changes are quantified from interframe differences. Using this data, a cinematic display of the functional pattern of filling and emptying may be created to provide the user with a different perspective on cardiac chamber dynamics. Preliminary results indicate that the cinematic display of the change in volume with time permits visualization of cardiac blood pool filling and emptying, delineates such structures as the pulmonary artery and beating atria, and may prove useful in the visualization of asynergies, bundle branch blocks, and other conduction abnormalities.
