Dynamic contrast enhanced MRI is maturing as a tool in contemporary cardiovascular medicine and quantifying cardiac perfusion is becoming clinically relevant. The purpose of this study is to understand the inter-study repeatability of a self-gated approach for quantification of myocardial perfusion. Nine subjects underwent self-gated regadenoson rest/stress imaging twice within 9.54.5 days. The systolic images showed good repeatability of the myocardial perfusion reserve, with a coefficient of variation similar to published gated studies.
