- Cardiovascular magnetic resonance (CMR) is an increasingly used imaging tool in cardiology. Initially, technical resources and access to trained staff were limited to a few centers. As scanners become more available and thanks to widespread training of cardiologists and technicians, CMR can now be performed in most cardiology centers. Without exposing the patient to ionizing radiation, a comprehensive cardiac study can be performed in 30–45 min, depending on clinical problem and scanner capabilities. A typical cardiac exam consists of anatomical images for gross anatomy and cine images for the evaluation of ventricular function. Depending on the clinical problem, a number of additional techniques can be added. Using chelated gadolinium contrast agents, first pass myocardial perfusion can be analyzed during pharmacological stress for the diagnosis of coronary artery disease. After injection of contrast in a peripheral vein, high resolution angiography can be performed. Phase contrast velocity maps (which despite the terminology it does not include contrast agents) can also be used to analyze intrathoracic vascular blood flow and flow velocity.
