Abstract :
Myocardial ischemia can be studied using multidimensional parametric or material property images of the heart obtained using ultrasound. The author describes methods suitable for both in vitro and in vivo evaluation of hearts from experimental animals and for in vivo human hearts. Regions of ischemia can be seen as early as 5 minutes after the blood flow has been terminated from regions of the myocardium. Multidimensional relationships can be seen using specialized three-dimensional imaging techniques
