Results from retrospective image sorting. In two subjects, perfusion difference images acquired during free breathing are shown (left), reconstructed from all 48 label-control pairs, and (right), after retrospectively sorting the images based on respiratory bellows position. During one quarter of the acquisition time, the subject was breathing deeply. The sorting strategy accepted the 50% of images closest to end-expiration. These images were acquired using the ‘heavy’ background suppression scheme.
