Abstract

Electrocardiographically gated magnetic resonance (MR) image acquisition is not optimal for the quantification of in vivo cardiac deformation, because of the cycle-length dependence of cardiac mechanical events. The authors developed a method for acquisition of cardiac MR images gated to the first derivative of leftventricular-developed pressure and used the method in a canine model. Application of this method may improve myocardial stress-strain analyses.
