Design outcomes

Primary

MeasureTime frame
Primary endpoint: the mean image quality score of the research protocol, determined from a subjective judgement by cardiologists, is not lower by more than 0.2 points compared with the mean image quality score of clinical protocol (non-inferiority test). See section 3.3 of the protocol for the statistical analysis.

Secondary

MeasureTime frame
Secondary endpoint: the mean image quality score is computed off-site by measuring the CNR in a vessel in the research and reference runs. With the outcome of these measurements, the CNR will be correlated with the subjectively scored image quality. The objective is to determine the minimal required CNR.
