Heart failure is a progressive disease with the potential for gradual deterioration. Non-invasive imaging techniques play a critical role in both assessing what caused the heart failure as well as monitoring the damage and deterioration of the heart. In this issue of Heart Failure Clinics, experts discuss a number of non-invasive imaging techniques including nuclear probes for assessing myocardial viability, hyperenhancement MRI, and novel techniques of ultrasound assessment and diastolic dysfunction.
