In the paper titled “Biodistribution and SPECT imaging study of   labeling NGR peptide in nude mice bearing human HepG2 hepatoma,” there is a mistake in the chemical structure of the NGR sequence and it is corrected in Figure 1 below. There is also a number mistake in the part of Materials and Methods (2.4. Cell Culture and Animal Model) that the HepG2 tumor model was established by subcutaneous injection of 5 × 106 HepG2 tumor cells (0.1 mL) into the right upper flanks, but not 2 × 106.
