In the article “18F-FDG PET Imaging in Neurodegenerative Dementing Disorders: Insights into Subtype Classification, Emerging Disease Categories, and Mixed Dementia with Copathologies,” by Minoshima et al. (*J Nucl Med*. 2022; 63:[2S–12S](https://doi.org/10.2967/jnumed.121.263194)), Figures 4 and 5 were switched. *Figure 4 should be Figure 5 and Figure 5 should be Figure 4; the legends are correct*. We regret the error.

In the article “Amyloid PET in Dementia Syndromes: A Chinese Multicenter Study,” by Shi et al. (*J Nucl Med.* 2020;61:[1814–1819](https://doi.org/10.2967/jnumed.119.240325)), the author line neglected to mention that *Zhihong Shi, Li-ping Fu, Nan Zhang, and Xiaobin Zhao also contributed equally to this work*. The authors regret the error.

In the article “Production and Supply of α-Particle -Emitting Radionuclides for Targeted α-Therapy,” by Radchenko et al. (*J Nucl Med*. 2021;62: [1495–1503](https://doi.org/10.2967/jnumed.120.261016)), affiliation 10 is incorrect. Bayer American Samoa should be *Bayer AS*. We regret the error.

In the article “177Lu-Prostate-Specific Membrane Antigen Ligand After 223Ra Treatment in Men with Bone-Metastatic Castration-Resistant Prostate Cancer: Real-World Clinical Experience,” by Sartor et al. (*J Nucl Med.* 2022;63:[410–414](https://doi.org/10.2967/jnumed.121.262240)), affiliation 9 is incorrect. The correct affiliation should be *Nuclear Medicine and Radiometabolic Unit, IRCCS Istituto Romagnolo per lo Studio dei Tumori (IRST) “Dino Amadori”, 47014 Meldola, Italy*. The authors regret the error.
