To evaluate potential issues, a question and answer session with a brief didactic lecture was given by an expert cardiovascular radiologist to the CT technologists and the nursing staff, including an overview of coronary artery imaging and the purpose of performing CCTA and FFRCT at our institution. To evaluate the effect of pre-scan medication use on overall CCTA image quality at our institution, the radiology nurses were instructed to give every patient nitroglycerine and a beta-blocker, if required and not contraindicated, to achieve a heart rate of <70 and preferably <60. A second random sample of 30 CCTA cases performed during the month of November 2019 was reviewed by the same expert cardiovascular radiologist to assess for early post-intervention changes following the initial medication changes to confirm that improvement could be seen in the visual quality score.	./cache/cord-267006-gsevwptc.txt	./txt/cord-267006-gsevwptc.txt
