ß-Blockers for Cardiac CT: A Primer for the Radiologist

OBJECTIVE. The objective of this article is to describe a protocol for the administration of ß-blockers for cardiac CT. A low and regular heart rate is necessary for optimal visualization of the coronary arteries on CT and can be achieved by the administration of medications.

CONCLUSION. Beta-blockers can be safely given, orally or IV, to most patients to lower the heart rate for cardiac CT. A protocol can be implemented and patients can be screened for certain contraindications to allow successful administration of these medications by radiologists.

Keywords: ß-blocker • cardiac imaging • coronary arteries • CT arteriography • MDCT
