| 99mTc-MDP bone SPECT | 740–1,110 MBq (20–37 mCi) | 833 MBq (23 mCi) | 1,185 MBq (32 mCi) | 925 MBq (25 mCi) | 999 MBq (27 mCi) | 23,100 MBq⋅min (625 mCi⋅min) | 25,000 MBq⋅min (675 mCi⋅min) |
| 18F-FDG whole-body PET | 148–740 MBq (4–20 mCi) | 555 MBq (15 mCi) | 710 MBq (19 mCi) | 518 MBq (14 mCi) | 592 MBq (16 mCi) | 1,554 MBq⋅min (42 mCi⋅min) | 1,776 MBq⋅min (48 mCi⋅min) |
↵* 99mTc-MDP bone SPECT values assume use of dual-head system with 25-min study duration. 18F-FDG whole-body PET values assume acquisition with 3 min per bed position.
