Utility of Perfusion Testing During Dobutamine Stress: Top Left Image: Resting mid-left ventricular short axis with no perfusion abnormalities. Top Right Image: Resting mid-left ventricular short axis slice after dobutamine stress demonstrating perfusion abnormalities in the inferior (red arrow) and anterolateral (yellow arrow) regions. Bottom Left Image: Left anterior oblique view of the SVG to distal RCA graft; red arrow points to a 70% lesion in the proximal body of the graft. Bottom Right Image: Right anterior oblique cranial view of the left coronary system; red arrow points to diffuse disease in the mid-and distal left anterior descending artery; yellow arrow points to a 60% lesion in the mid-circumflex coronary artery.

Figure 6: Utility of Perfusion Testing During Dobutamine Stress: Top Left Image: Resting mid-left ventricular short axis with no perfusion abnormalities. Top Right Image: Resting mid-left ventricular short axis slice after dobutamine stress demonstrating perfusion abnormalities in the inferior (red arrow) and anterolateral (yellow arrow) regions. Bottom Left Image: Left anterior oblique view of the SVG to distal RCA graft; red arrow points to a 70% lesion in the proximal body of the graft. Bottom Right Image: Right anterior oblique cranial view of the left coronary system; red arrow points to diffuse disease in the mid-and distal left anterior descending artery; yellow arrow points to a 60% lesion in the mid-circumflex coronary artery.

Mentions: Finally, the results (positive or negative for ischemia) of either wall motion or perfusion stress tests did not add incremental information regarding CV prognosis in individuals with a severely reduced LV ejection fraction at rest (Figure 6). The results of this large study suggest one should consider stress CMR imaging strategies according to patient co-morbidities on an individualized basis. In some individuals wall motion analyses may be sufficient; whereas in others, wall motion may need supplementation with perfusion imaging.
