In Table 6 of the article “Tissue Distribution of 18F-FDG-Labeled Peripheral Hematopoietic Stem Cells After Intracoronary Administration in Patients with Myocardial Infarction,” by Kang et al. (J Nucl Med. 2006;47:1295–1301), the unit of measure for radiation dose was mistakenly stated to be mGy/Bq instead of the correct unit, mGy/MBq. The authors regret the error.
