In the article “Pharmacologic Stress Testing with Myocardial Perfusion Imaging” by Pagnanelli and Camposano (J Nucl Med Technol. 2017;45:249–252), 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.
