Primary outcomePrimary: Agreement and Correlation of Coronary Artery Calcium Score Obtained From Ultra-low-dose and Standard CT — 212; 178 Agatston score
Summary
The aim of the study is to compare the CACS obtained from standard dose CT to the CACS obtained from ultra-low-dose scans. Additionally, the usefulness of ultra-low-dose CT for AC of myocardial perfusion SPECT will be assessed.
