Abstract Background: The calcium score is an imaging test used to evaluate cardiovascular risk by detecting coronary artery calcification (CAC). However, exposure to ionizing radiation during computed tomography (CT) has been a concern. Objective: The objective of this study was to evaluate radiation dose and the diagnostic quality of the calcium score using reduced tube voltage and iterative image reconstruction. Methods: This was a cross-sectional, observational study with patients over 18 years of age. Patients with previous coronary artery disease […]
