Table 4 Signal-to-noise ratio with and without metal artifact reduction, median (25^th percentile, 75^th percentile)

Observer	With MAR	Without MAR	Reference	P value
One	17.3 (8.5-30.2)	8.03 (1.99-26)	17.6 (6.65-42.5)	0.057
Two	12.98 (7.68-41.8)	5.74 (2.88-23.6)^a	19.1 (8.2-36.5)	0.009
Three	16.5 (5.5-40.6)	6.5 (3.0-15.8)^a	16.8 (7.1-43.0)	0.004

^aP < 0.05 signal-to-noise ratio without metal artifact reduction vs signal-to-noise ratio with metal artifact reduction.

Test of significance is Friedman’s test. MAR: Metal artifact reduction.
