As 211At-MABG does not emit gamma-rays suitable for dosimetry and imaging, 211At-MABG needs a companion diagnostic imaging agent such as meta-[123I]iodobenzylguanidine (123I-MIBG) to be used in making treatment decisions. We evaluated the similarities and differences between 123I-MIBG and 211At-MABG in biodistribution in normal mice. BALB/c mice were injected with 123I-MIBG or 211At-MABG, and the radioactivity levels (%ID/g) in the tissues were determined at 1 and 30 min, and 1, 3, 6, and 24 h after the injection. Results: 211At-MABG and 123I-MIBG showed very similar biodistribution profiles in normal mice at every time point. Conclusions: 123I-MIBG can be used for dosimetry and imaging for decisions regarding treatment with 211At-MABG radiotherapy., 第59回日本核医学会学術総会}, title = {正常マウスにおける123I-MIBGと211At-MABGの体内動態の評価}, year = {2019} }
