Answer

Myocardial perfusion imaging is a valuable method for triaging patients with chest pain in the ED. Myocardial perfusion imaging at rest is highly sensitive for detecting acute MI, and it can be supplemented with provocative testing after infarction is excluded. However, the results of clinical trials can be applied only in centers with proven reliability and experience.
