Abstract

Purpose: [¹⁸F]AV-1451 is a positron emission tomography (PET) radioligand for detecting paired helical filament tau. Our aim was to estimate the radiation dose of [¹⁸F]AV-1451 in humans. Procedures: Whole-body PET scans were acquired for six healthy volunteers (three male, three female) for 128 min after injection of [¹⁸F]AV-1451 (268 ± 31 MBq). Radiation doses were estimated using the OLINDA/EXM software. Results: The estimated organ doses ranged from 7.81 to 81.2 μSv/MBq. The critical organ for radiation burden was the liver. Radiation doses to the reproductive and blood-forming organs were 14.15, 8.43, and 18.35 μSv/MBq for the ovaries, testes, and red marrow, respectively. The mean effective dose was 22.47 ± 3.59 μSv/MBq. Conclusions: A standard single injection of 185 MBq (5 mCi) results in an effective dose of 4.7 mSv in a healthy subject. Therefore, [¹⁸F]AV-1451 could be used in multiple PET scans of the same subject per year.
