Uses
In the investigation of cardiovascular disease the physician has a wide variety of tools available. The key disadvantages of CMR are limited availability, expense, and special skills/technical training needed to perform CMR (vs other types of MRI). The key advantages are image quality, non-invasiveness, accuracy, versatility and no ionising radiation.
MRA (magnetic resonance angiography) can produce 3D and 4D images of blood vessels and the flow of blood through the vessels.
