Figure 1 Examples of Agreement Between the 2 Field Strengths for the Identification of Significant Coronary Artery Disease
The angiogram of Patient #1 (top row) in the right lateral (right anterior oblique 90°) projection demonstrates a subtotally occluded left anterior descending (LAD) coronary artery after the bifurcation of the first diagonal (between the 2 full black arrows). The LAD continues partially filled (indicated by the 3 intermittent black arrows) and the LAD territory is partially collateralized from the diagonal branch. There are corresponding stress perfusion deficits in the anteroseptal and inferoseptal segments at both field strengths (white arrows). Patient #2 (bottom row) had a 70% stenosis in the right coronary artery, with corresponding perfusion deficits at 1.5- and 3-Tesla (T) imaging (white arrows).
