Subendocardial steal effect seen with real-time perfusion imaging at low emission power during adenosine stress: replenishment M-mode processing allows visualization of vertical steal.
We present a patient in whom power pulse inversion imaging clearly demonstrated a subendocardial myocardial perfusion defect during contrast vasodilator stress using adenosine. The defect was best appreciated with M-mode postprocessing of power pulse inversion imaging data.
