Comparison of DIR and DW prepared T2-weighted images during Dobutamine hyperemia in a LAD stenotic dog. Although blood signal in the left ventricle appears to be suppressed, the irregular ECG triggering and fast heart beats (~180/min) resulted in "spillover artifacts" from unsaturated blood signals, as shown in the anterior regions of DIR images (hyperintensity, arrows). In contrast, DW images demonstrate the expected lower signals in the anterior regions (block arrows) resulting from 90% LAD stenosis. LV = left ventricle.
