Figure 6 Effect of Contrast Agent Use on the Sensitivity and Specificity of DSE

The effect of contrast agent use on the sensitivity and specificity of dobutamine stress echocardiography (DSE) for coronary artery disease is shown, grouped by confidence of interpretation in unenhanced studies. Only interpretable studies are included in the analysis. A trend was seen mostly for improvement in specificity in low- to medium-confidence studies and a lesser improvement in sensitivity, and a trend for worsening in specificity was observed in unenhanced studies interpreted with high confidence.
