CMR

Cardiac MR stress testing is more accurate than SPECT, is a strong predictor of cardiac events and survival, and is cost-effective in the evaluation of patients with chest pain.

Cardiac MR is safe for all prosthetic heart valves and intracoronary stents.

Gadolinium-based contrast agents carry a risk of nephrogenic systemic fibrosis in patients with eGFR <30, but this risk is very low with current cyclic contrast agents.

To assess myocardial viability in patients with chronic coronary heart disease, cardiac MR with late gadolinium enhancement has the best sensitivity for recovery of function with revascularization, but low-dose dobutamine contractile reserve has better specificity.
