Corrigendum to “¹³¹I-labeled chitosan hydrogels for radioembolization: a preclinical study in small animals” [Nucl Med Biol 52 (2017) 16–23] (S0969805117300896) (10.1016/j.nucmedbio.2017.05.006))

The authors regret that there were typographical errors in the description of ¹³¹I Chi biodistribution results. Our ¹³¹I Chi biodistribution data were correctly used in Figure 6B. However, the descriptions in the result section ‘Whole body imaging of ¹³¹I Chi and biodistribution’ were mistakenly drawn from a wrong data set. This inadvertent error was not detected prior to publication. Below are the correct descriptions. Whole body imaging of ¹³¹I Chi and biodistribution Whole body gamma images (Fig. 6A) showed liver accumulation of ¹²⁵I Chi in vivo. Biodistribution of ¹²⁵I Chi was examined to determine stability of our radioactive iodine and distribution ex vivo (Figure 6B). A large fraction of ¹²⁵I Chi administered was accumulated in the liver. The mean liver accumulations were 86.46 ± 3.19%ID at 1 d, 76.75 ± 7.83%ID at 2 d, 71.89 ± 4.21%ID at 4 d, 70.67 ± 0.48%ID at 7 d, 67.53 ± 0.16%ID at 14 d, and 64.68 ± 0.08%ID at 28 d after treatment. Extrahepatic retention was insignificant except that a small fraction of ¹²⁵I Chi was detected in the stomach (2.02 ± 3.07%ID) and muscle (1.37 ± 1.48%ID) at 2 d. The authors would like to apologize for any inconvenience caused.
