[Cardiac computed tomography and magnetic resonance imaging in patients with coronary artery disease].
Coronary angiography by computed tomography (CTCA) is most suitable for symptomatic patients with an intermediate likelihood to exclude a coronary stenosis as the cause of the symptoms. It would also be appropriate in a patient in whom an equivoval stress test result has led to uncertainty about the patient's further management. CTCA may occasionally be acceptable in a high risk symptomatic patient who refuses the necessary invasive coronary angiography if the results of CTCA are likely to alter patient management.The main indication for cardiac magnetic resonance imaging (CMR) is for pharmacologic stress testing. If such a test is indicated, dobutamine stress CMR is an alternative to stress echocardiography and adenosine perfusion CMR is the alternative to nuclear myocardial perfusion imaging but without radiation. Late gadolinium enhancement CMR is the current gold standard for the assessment of myocardial scars and hence is well suited to predict recovery of function in dysfunctional myocardial regions following revascularisation (viability testing).
