Exclusion criteria
Exclusion criteria: · Patient with a heart rate > 65 beats per minute (bpm) and contraindication or intolerance to b-blocker administration. · Patient with arrhythmia or non-sinus rhythm. · Patient unable to sustain breath hold. · Patient with decompensated heart failure. · Patient with evidence of ongoing or active clinical instability (suspected or known acute myocardial infarction, cardiac shock, acute pulmonary oedema). · Patient who has previously undergone coronary artery bypass graft (CABG). · Patient who has previously undergone percutaneous transluminal coronary stent placement. · Patient with artificial heart valve. · Patient with known moderate to severe aortic stenosis. · Patient with known hyperthyreosis (thyroid-stimulating hormone 1.5 mg/dl or > 120µmol/l) or estimated creatinine clearance < 30 ml/min as calculated by the Cockcroft and Gault formula or e-GFR < 30ml/min/1.73m²). · Patient previously included in this trial or having participated in any investigational drug study within 30 days prior the study enrolment or included in another clinical trial involving an Investigational Medicinal Product (IMP). · Any condition which, based on the investigator's clinical judgement, would prevent the patient from completing all trial assessments and visits (e.g.: mental or physical incapacity, language comprehension, geographical localisation, etc…). · Patient under guardianship and/or inability or unwillingness to cooperate with the requirements of this trial. · Breast feeding or pregnant patient.

| Main Objective: To demonstrate the statistical non-inferiority of Xenetix® 350 compared to Ultravist® 370 and Iomeron® 400 when used in coronary angiography in terms of CT scan evaluability (quality and interpretability of images). ;Secondary Objective: - To compare the three contrast media on several qualitative and quantitative efficacy parameters (image quality, stenosis assessment, signal quantification, coronary track rate, calcium scoring, radiation dose, patient comfort and management). - To compare the clinical and electrocardiographic tolerance of the three contrast media.;Primary end point(s): Evaluability of CT scans based upon the assessment of 18 segments from the SCCT coronary segmentation, using a 5-point evaluation scale grading the quality and the interpretability of images from non-diagnostic (major doubts about presence/absence of stenosis) to excellent (not any doubts about presence/absence of stenosis). From the segment-level assessment, CT scan evaluability will defined as the proportion of patients presenting with no non-diagnostic segments (except occluded segments) | — |
