Fig. 4.

Reslice analysis in control and infarcted mice. Representative contrast images at time (t) = 8 s are shown for a control (A) and an infarcted (E) mouse. The white solid line represents the one-dimensional region of interest (ROI) used to create the reslice images. Arrows in E and H denote the extent of the perfusion defect. Corresponding B-mode images and triphenyltetrazolium chloride (TTC) stains are shown in B and F and in C and G, respectively. Red TTC staining represents viable myocardium, whereas white regions are nonviable. Reslice images, depicting contrast intensity along the length of the ROI (vertical dimension) over time (horizontal dimension) are shown in D and H.
