Examples of discarded (left) and chosen (right) acquisitions from four different protocols. (a) 2D FLAIR (considerable vs. no bulk patient motion), (b) MRA 3D SPACE STIR (considerable vs. moderate breathing motion), (c) Cine SSFP SAX (mistriggering vs. correct electrocardiographic gating), (d) T1w 3D VIBE DIXON (with vs. without fat–water swap artifact in the liver). The images in each pair were acquired with identical setups and taken from identical participants. In the NAKO MRI study, protocols were repeated if the initial acquisition did not meet the SOP, if severe image artifacts occurred, or if the image quality was otherwise unsatisfactory to the examining radiologic technologist.
