Answer

The role of imaging in the work-up of acute myocardial infarction (MI) is broad, but the procedures are primarily used to confirm or rule out coronary artery disease (CAD). Furthermore, imaging may help to define the anatomy and degree of myocardial perfusion abnormalities. In lower-risk individuals in whom acute coronary syndrome (ACS) is suspected and who do not have serial electrocardiographic (ECG) changes or positive serial cardiac biomarker findings, some form of stress testing may help to confirm the diagnosis and guide therapy.
