Table 3 Lesion detectability and inter-rater reliability for each simulated activity reduction

From: Reduction of [⁶⁸Ga]Ga-DOTA-TATE injected activity for digital PET/MR in comparison with analogue PET/CT

	Number of lesions
	50%-β600*	33%-β450	17%-β450	0%-β300
Reader 1	68	67	74	76
Reader 2	58	68	73	77
ICC (95% CI)	0.96 (0.90–0.98)	0.98 (0.97–0.99)	0.97 (0.94–0.99)	0.97 (0.94–0.99)

Statistically significant differences (p ≤ 0.05) in mean visual score compared with 0% simulated activity reduction with factor β = 300 determined by Friedman test with additional Dunn’s multiple comparisons test are indicated with asterisks
