Figure 2 Color-coded wall-motion analysis of the LV (Patient 1) was derived from gated PET (red = max. amplitude). The anteroseptal and inferoseptal view showed akinesia of the entire anteroseptal and apical region.

Figure 3 The corresponding picture of glucose metabolism (Patient 1) shows normal-to-increased glucose metabolism in the akinetic anterosepal region (red = max. intensity). In the apical region the reduced intensity indicates a nontransmural infarction.
