Box plot illustrating the absolute and relative reduction of artifact size in comparison to LAVA-Flex. (a) Box plot illustrating the absolute reduction of artifact size in comparison to LAVA-Flex (mm2). All three sequences show a broad spread of reduction, reaching from 4 up to 2,010 mm2 for T1-FSE, 12 up to 2,288 mm2 for MAVRIC, and from 39 up to 2,209 mm2 for MAVRIC-fast (Table 1). (b) Box plot illustrating the relative reduction of artifact size in comparison to LAVA-Flex (%). The relative artifact reduction was significantly higher for MAVRIC sequences compared to T1-FSE, with a mean of −62% for the T1-FSE sequence, −75% for MAVRIC, and −78% for MAVRIC-fast (Table 1).
