In the article “Performance Measurements of the Siemens mMR Integrated Whole-Body PET/MR Scanner,” by Delso et al. (J Nucl Med. 2011; 52:1–9), the time resolution provided for the Siemens Biograph mMR should have been 3.6 ns instead of 2.93 ns. The authors regret the error.
The center panel of Figure 3B was incorrect in the article “Stratification of Nucleoside Analog Chemotherapy Using 1-(2′-Deoxy-2′-18F-Fluoro-β-d-Arabinofuranosyl)Cytosine and 1-(2′-Deoxy-2′-18F-Fluoro-β-l-Arabinofuranosyl)-5-Methylcytosine PET,” by Lee et al. (J Nucl Med. 2012; 53:275–280). The corrected figure appears below. We regret the error.
