Figure 5 Impact of Contrast Agent Use on Accuracy of DSE in Relation to Confidence of Interpretation in Unenhanced DSE Studies

There was no impact of contrast agent use on the agreement of dobutamine stress echocardiography (DSE) with angiography (accuracy) if the confidence of interpretation was high in unenhanced studies. However, a significant impact was seen when the confidence of interpretation was low, with an intermediate effect in studies with medium confidence.
