Erratum ======= In the article “Pharmacologic Stress Testing with Myocardial Perfusion Imaging” by Pagnanelli and Camposano (*J Nucl Med Technol*. 2017;45:[249–252](http://tech.snmjournals.org/lookup/volpage/45/249)), the “Dipyridamole” section incorrectly states that the dipyridamole dosage is “*0.142* μg/kg/min, or *0.57* μg/kg (*2*).” The corrected sentence should read “The dosage is *142* μg/kg/min, or *570* μg/kg (*2*).” In addition, the “Adenosine” section incorrectly states that the indicated dose for adenosine is “*0.14* μg/kg/min.” The corrected sentence should read “The indicated dose for adenosine is *140* μg/kg/min.” The authors regret the error.
