Defining Roles: Where Does Cardiac MR Fit in?

摘要

Cardiac MR has a few inherent advantages over other cardiac imaging modalities. With radiation exposure and patient safety concerns at a crescendo, cardiac MR benefits from not requiring ionizing radiation or iodinated contrast. MRI also provides flexibility in its capability to assess numerous parameters of cardiovascular anatomy and function. It can characterize tissue composition and offers unique information about the presence and extent of myocardial scar. Cardiac MR also can quantify blood flow and measure heart wall motion.
