Subjective image quality for the mDixon and subtraction methods averaged for both readers.

Anatomical location	Imaging method	Mean score ± SD	P-value
Total	mDixon	2.88 ± 0.32
	Subtraction	2.57 ± 0.48	<0.001
Abdominal position	mDixon	2.99 ± 0.08
	Subtraction	2.75 ± 0.28	<0.001
Upper leg position	mDixon	2.97 ± 0.15
	Subtraction	2.68 ± 0.37	<0.001
Lower leg position	mDixon	2.60 ± 0.50
	Subtraction	2.13 ± 0.60	<0.001

SD, Standard deviation; Score: 0, not evaluable, no arteries visible (non-diagnostic); 1, poor to moderate quality, not all arterial segments evaluable due to noise, heterogeneous vascular enhancement or poor fat suppression (partly non-diagnostic); 2, acceptable quality but some noise or heterogeneous signal, all arterial segments evaluable for diagnostic purposes; 3, good quality, all arterial segments evaluable for diagnostic purposes without artifacts.
