Zusammenfassung:Purpose To optimize and evaluate an ultra-low-dose (ULD) technique for CT coronary angiography (CTCA). Materials and methods Eighty-two patients were randomly divided into two groups. ULD and routine CTCA were performed in groups A and B. Image quality, radiation dose and contrast agent were evaluated. Results The effective dose (ED) was 0.20 ± 0.01 mSv for the ULD technique, a decrease of 87% ( t  = − 21.182, P
