Combined assessment of wall motion from cine imaging and perfusion defects from first-pass perfusion imaging has been shown to have a high diagnostic performance for detection of acute ischemia. In this work, we demonstrate the feasibility and effectiveness of ungated cardiac-phase resolved (cine) first-pass imaging for concurrent imaging of myocardial wall motion and perfusion in an animal model with flow-limiting stenosis.
