Current spectrum of indications for cardiac CT

Clinical indication	Gained knowledge
Asymptomatic individual with intermediate risk	Calcium score improves risk classification and can guide preventive therapy
Suspected coronary artery disease	Exclusion of obstructive coronary artery disease leads to more appropriate patient management Potentially obstructive coronary artery disease improves referral for angiography Detection of non-obstructive disease and high-risk plaque features offers opportunity for preventive treatment
Acute chest pain and acute coronary syndrome cannot be ruled out	Exclusion of obstructive coronary artery disease shortens length of stay in the emergency department and allows safe discharge
Recurrent chest pain after coronary intervention	Evaluation of stent and graft patency, in selected cases
Pre-procedural imaging for transcatheter valve repair / replacement	Pre-procedural planning by visualizing the target anatomy and obtaining the necessary measurements as well as evaluation of the different access routes
Prosthetic valve assessment in suspected dysfunction or endocarditis	Determination of the cause of dysfunction by visualizing the anatomic substrate and the presence of valve vegetations and perivalvular mycotic aneurysms, in selected cases
Pre-left atrial ablation	Pre-procedural planning by visualizing the interatrial septum, left atrium/appendage and pulmonary veins, and evaluating relevant anatomical variants
