1) Understand that perfusion MRI can be implemented in every radiology department. 2) Learn how to differentiate normal from abnormal perfusion of the myocardium. 3) Compare the performance of perfusion MRI with other imaging modalities. 4) Identify indications and patient populations for perfusion MRI.
Adenosine stress MR myocardial perfusion imaging has a proven high sensitivity and negative predictive value for the detection of myocardial ischemia. High diagnostic accuracies are reached in patient groups with relatively high prevalence of disease in studies combining rest-stress perfusion and delayed contrast enhancement. For the subgroup of patients with a history of myocardial infarction these elaborate protocols or different stress MR imaging methods are probably most appropriate. In relatively lower risk patients, those without known myocardial infarction, less comprehensive protocols are effective to guide further work-up and therapy choice. In lower-risk patient groups examined by adenosine stress-only perfusion MR imaging the number of purely diagnostic coronary angiographies (CAG’s) can be reduced and almost ruled out.
