FIGURE 2. DE-MRI images and corresponding SPECT images in patient with extensive infarcted regions. Defect quantification results were 27% by DE-MRI, 31% by SPECT EXT, and 25% by SPECT TPD. (Top row) DE-MRI image (A), coregistered slice from delayed 201Tl rest SPECT (B), and fused MRI/SPECT image (C). (Bottom row) Definition of infarct regions (red) and LV contours (blue) on DE-MRI image (D), LV contours on corresponding SPECT slice (E), and polar map SPECT quantification (F). Arrows point to defect locations in A and B. DE-MRI scan contains no-reflow zones in inferior wall hyperenhancement region. No-reflow zones were included by the operator in overall infarct region. Note that anterior wall infarct was clearly resolved by SPECT despite being nontransmural.
