In vivo quantification of brain serotonin transporters in humans using[11C]McN 5652

There was a typographical error in the article, “In Vivo Quantification of Brain Serotonin Transporters in Humans Using [¹¹C]McN 5652,” by Parsey et al. (JNM 2000;40: 1465–1477). The last sentence in the 8th paragraph of the Discussion section should read: “Because this method was used in the measurement of 5-HT transporters in chronic 3,4-methylenedioxymethamphetamine abusers, the results of this study should be viewed with caution (35).”
