Figure 3From: Cine and tagged cardiovascular magnetic resonance imaging in normal rat at 1.5 T: a rest and stress studyWall thickening and circumferential strain at endocardial, midwall and epicardial levels measurements. All measurements under dobutamine stress are significantly different from the values obtained at rest, except for circumferential strain at epicardial at 2.5 μg/min/kg. (*: p < 0.05 vs 0; †: p < 0.05 vs 2.5; ‡:p < 0.05 vs 5 μg/min/kg).Back to article page
