Erratum to “Biodistribution and SPECT Imaging Study of ^99mTc Labeling NGR Peptide in Nude Mice Bearing Human HepG2 Hepatoma”

In the paper titled “Biodistribution and SPECT imaging study of^99mTc 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.
