Cohen’s kappa coefficients for inter-rater variability of differentiation score in all lesions and in subgroups, based on the lesion SUVmax and size

Group	PET/Dixon	PET/ZTE
All lung lesions	0.641 (0.569–0.713)	0.723 (0.663–0.783)
SUVmax < 1	0.577 (0.459–0.695)	0.591 (0.455–0.727)
SUVmax 1–3	0.516 (0.375–0.658)	0.635 (0.528–0.743)
SUVmax ≥ 3	0.582 (0.402–0.762)	0.792 (0.668–0.916)
Size < 4 mm	0.580 (0.427–0.734)	0.650 (0.523–0.778)
Size 4–6 mm	0.653 (0.533–0.773)	0.745 (0.646–0.844)
Size 6–8 mm	0.659 (0.495–0.823)	0.718 (0.589–0.846)
Size ≥ 8 mm	0.551 (0.378–0.724)	0.686 (0.536–0.837)
