Early detection of coronary atherosclerotic disease facilitates adequate prevention. The purpose of this study is to compare an assessment of coronary atherosclerotic disease burden by positron emission tomography / computed tomography (NaF-PET/CT) with those of conventional and ultra-high-resolution-CT (UHR-CT) in patients with suspected coronary artery disease. For this purpose, the investigators plan to include 33 patients with symptoms concerning for CAD who have been referred for cardiac CT testing.
Male or female patients
18 years or older
referred for coronary CT angiography because of suspected coronary heart disease (CHD) with stable symptoms
The patient has a history of coronary heart disease, defined by prior myocardial infarction or prior coronary artery revascularization.

Morbid obesity defines as a body mass index of >40.
