Figure 1From: Cardiac magnetic resonance myocardial feature tracking detects quantitative wall motion during dobutamine stressThe figure shows changes in circumferential and radial strain in respect to changes of left ventricular ejection fraction (EF) at rest and with dobutamine stress (10 and 20 μg/kg-1/min-1). LV=left ventricle, EF=ejection fraction.Back to article page
