Abstract
This erratum corrects an error in “Measuring temporal stability of positron emission tomography standardized uptake value bias using long-lived sources in a multicenter network,” by D. Byrd et al.

This article [J. Med. Imag. 5(1), 011016 (2018), doi: 10.1117/1.JMI.5.1.011016] was originally published online on 4 January 2018 with the following error. The Pearson correlation coefficients were not computed and reported in a consistent fashion, most notably in Table 10, where values labeled “r2” were instead the values of r without appropriate squaring. Figure 8 contained a similar inconsistency, though not all values were affected.

Original (erroneous) and corrected correlation coefficients from Table 10 are enlisted here with their corresponding measurements:
