In the article “Direct Imaging of Radionuclide-Produced Electrons and Positrons with an Ultrathin Phosphor,” by Chen et al. (J Nucl Med. 2008;49:1141–1145), reference 11 was cited incorrectly. The correct citation is as follows: Cho JS, Vu NT, Chung YH, et al. Detection of beta particles in a microfluidic chip using a scintillator and CCD. In: 2006 IEEE Nuclear Science Symposium Conference Record. Piscataway, NJ: IEEE; 2006:1977–1981. The authors regret the error.
The authors of “Combination Therapy and Noninvasive Imaging with a Dual Therapeutic Vector Expressing MDR1 Short Hairpin RNA and a Sodium Iodide Symporter,” by Park et al. (J Nucl Med. 2008;49:1480–1488), would like to rectify a mistake in the surname of the third author of the article. The correct surname is Thapa. The authors regret the error.
