FIGURE 8. Coregistration of delayed contrast enhancement cardiac MR viability images with ¹⁸F-FDG viability images. (A) MRI, (B) (PET/MRI image fusion), and (C) PET demonstrate concordance, with reduced metabolic activity in regions of near-transmural myocardial scarring in septum and lateral wall (arrows), as seen in left ventricular short-axis imaging plane.
