Figure 1

Perfusion images from a HF patient with a circumflex coronary artery lesion causing a perfusion abnormality extending from base (A) to mid (B) to apical (C) level. Images seen vertically on the right show the perfusion maps corresponding to the ventricular level, the central column shows superimposed images. Note that there is mild respiratory artifact (white arrows) and that dark rim artifact seen in the apical inferoseptal wall (orange arrow).
