Figure 7 Effect of Contrast Agent Use on Accuracy of DSE in Relation to the Number of Segments Visualized

A significant impact of the use of a contrast agent on accuracy of dobutamine stress echocardiography (DSE) was seen when >2 myocardial segments were not visualized in unenhanced studies. Lesser impact was seen when 1 to 2 segments were not seen, and no impact was observed if all segments were already visualized.
