ASL images reconstructed from multiple combinations of the data acquired in the representative volunteer using interleaved PCASL-PROMO sequence in the presence of random motion. Reference: ASL images without PROMO in the absence of any intended motion. PROMO on/off: ASL images with/without PROMO. Apply only: ASL images with real-time updating of the coordinate system only (without rescanning of corrupted segments). Rescan tagged/control only: ASL images with real-time updating of the coordinate system and with rescanning (either tagged or control images only). ASL images with apply only showed significantly reduced motion artifacts compared with images without PROMO, although residual blurring exists. Images in which rescanning was only applied to motion-corrupted tagged images were closer to the images with full PROMO correction than those with rescanning of motion-corrupted control images.
