Figure 2 Visualization of Segments by View at Peak Stress: Contrast Agent Versus Noncontrast Enhancement

With the use of a contrast agent, an increase in percentage of segments with excellent or adequate endocardial visualization (score 1) was seen in all echocardiographic views, with a larger impact in the apical views. PLA = parasternal long axis; SAX = short axis; 4C and 2C = 4 and 2 chambers.
