The document discusses various cardiac tests that can be used to answer clinical questions about a patient's condition. It describes tests such as physical exams, echocardiograms, nuclear medicine tests, cardiac CT, and cardiac MRI that provide information on risk factors, existing diseases, signs and symptoms, and the progression of cardiac disease. Examples of specific views and images from these tests are also shown to illustrate what details they can reveal about the heart and blood vessels.
