Inclusion criteria

Inclusion criteria: • Coronary CT angiography performed within clinical routine • Stable heart rate below 65 beats per minute to be tested with low-dose technique

Exclusion criteria

Exclusion criteria: • arrhythmia • Heart rate = 65 beats per minute • Allergy to iodinated contrast agent • renal failure • hyperthyroidism

Design outcomes

Primary

MeasureTime frame
The primary endpoint is the achieved CT density in the left ventricle as well as in the aortic bulbus. The CT density is systematically analyzed in all patients after completion of the recruitment. Therefore, in the CT data the average CT density is determined in a 1 cm² measurement in the left ventricular cavity as well as in the aortic bulbus.

Secondary

MeasureTime frame
Overall image quality of the coronary arteries using a semi-quantitative Image quality score (Grade 1-4)
