Figure 1b. Images obtained in a 65-year-old man with anterior MI. LV = left ventricle.(a) Long-axis view (two cavities) obtained with delayed phase CT shows a late defect in the subendocardial part of the myocardium, along the anterior and apical wall of the left ventricle (arrows). This late defect is surrounded by a large area of hyperenhancement (arrowheads). Five segments (eg, segments 7, 8, 13, 14, and 17) were involved according to the 17-segment model analysis. (b) Short-axis view (two cavities) obtained 6 weeks later with SPECT shows persistent perfusion defect (arrows) in the anterior wall of the left ventricle corresponding to fixed MI. Five segments (eg, segments 7, 8, 13, 14, and 17) with residual defect were detected.
