*All sequences in the table were used in the conventional liver scan, whereas the items marked with * were used in the abbreviated protocol. For the DWI sequence, b = 50 s/mm² and 1000 s/mm² were both acquired in the conventional liver scan, whereas only b = 1000 s/mm² was acquired in the abbreviated protocol.

**TR is an assumed respiration period of the human adult. The actual TR varied with the actual respiration period of the patients.

^#Post-contrast FS T1 VIBE was acquired three times.
