Reduction in Radiation Exposure using a Focused Low-Voltage scan before Coronary CT Angiography

The integration of cardiac computed tomography (CCT) as a noninvasive imaging modality within clinical care has provided a unique platform for the assessment of anatomy and physiology in patients at risk or suspected of having cardiovascular disease. This has been propelled by developments in hardware and software with gantry rotation speeds fast enough to produce diagnostic images of the heart and coronary circulation. As an example of the initial application of CCT, the quantitative assessment of coronary artery calcification (CAC), through the well-validated Agatston score, has become a cornerstone in guiding clinician –patient discussion in intermediate-risk asymptomatic patients (1).
