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.
