Summary

A growing body of research and technological advancement suggests that magnetic resonance imaging (MRI) of the chest and heart will play a prominent role in future screening and monitoring of appropriate patients. MRI has the advantage of obtaining high-resolution 3D images non-invasively without the use of contrast. MRI of the chest and heart with its high spatial resolution and tissue blood contrast may identify incidental structures such as cardiac masses, congenital malformations, or pulmonary tumors. Cost and on-call availability are the major limitations of using MRI of the chest and heart regularly. Plain films and ultrasound have benefited from drastic reductions in cost and easy accessibility in EDs. The second significant limitation is the time required to image patients using MRI. Medical equipment for intubation, ECG leads, and patient lines have been engineered to be MRI compatible.
