Coregistration of MRI and PET images. Coregistration of MRI and FDG PET images of a control (top) and an atherosclerotic rabbit (bottom). Each row shows the fused dataset progressing from an anatomical MRI to a sole functional FDG PET image of the same animal in the same location. ROIs of the aorta (indicated with a blue circle and arrow) were identified on the MRI. The software automatically extracted the PET values from the same location in the PET image.
