Coronary Artery Calcification Assessed on PET Scanner (PET : Positron Emission Tomography)

Calcification artery calcium (CAC) scoring is a valuable tool for determining the risk of major adverse cardiac events. It was found that CAC can be quantitatively assessed, by manual scoring or using deep-learning, on low-dose non electrocardiogram-gated, contrast-enhanced or non-enhanced computed tomography (CT-scan) performed in association of PET acquisition, with a good agreement with standard scans. The purpose of this study is to determine the impact of a systematic coronary artery calcification evaluation in patients undergoing flourine-18 fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) imaging to improve primary prevention of cardiovascular diseases. A visual calcification artery calcium assessment will be made for each patient, dividing them into four groups: none, mild, moderate or heavy calcification artery calcium. When possible, a calcification artery calcium score will be computed. Each patient will complete a questionnaire to collect risk factors, history of cardiovascular diseases and medications.
