The article “Labeling of Cerebral Amyloid β Deposits In Vivo Using Intranasal Basic Fibroblast Growth Factor and Serum Amyloid P Component in Mice,” by Shi et al. (J Nucl Med. 2002;43:1044–1051), contains an error in the reported concentration of injected 125I-bFGF. The third sentence in column 2 of page 1045 should read “For mice in the first 2 groups, 6 drops (1.5 μL each) of 125I-bFGF (1.85 MBq/mL per 10 g of body weight) were injected by a tapered-end plastic tip to each nostril, 1 drop every 5 min with the mouse supine.” The authors regret the error.
