Root mean squared deviations Δ_i of D_ha from D_t (MBq) for approaches 1–4 and activities derived from the EANM equations SOP 8 and 9 of Marinelli and Bockisch, respectively

	TUG	NTG	TMG	GD
Δ1	789	318	196	264
Δ2	278	77	70	156
Δ3	215	51	74	131

Smallest deviations of D_ha from D_t were found for activity calculations based on the current EANM SOP across all disease entities. Results of pair-wise t tests are displayed in Fig. 1b
