Gadolinium-enhanced MRI of a cardiac radiation therapy patient at baseline (left) and 3 months post-treatment (right). Top: the left ventricle with patchy, gadolinium-enhanced scar was transmurally targeted with a radiation ose of 25 Gy between 3 and 6 o’clock (red brackets). Nonenhanced, remote myocardium is adjacent to target region (white arrowhead). Bottom: surviving nonenhanced myocardium within the same images is visible in the targeted region at baseline and 3 months post-treatment (yellow outline). See more figures from this study.
