Fig. 5.

Correlation of [¹⁸F]Galacto-RGD uptake and myocardial blood flow. Results are shown for all myocardial segments (17-segment model; A) and for the infarcted segments only (B, threshold below 0.5 ml/min/g). A significant but moderate inverse correlation of [¹⁸F]Galacto-RGD uptake and blood flow for all segments was measured. Note, however, that some segments showed intense [¹⁸F]Galacto-RGD uptake but only slightly or no impaired blood flow. This corresponds to the visual analysis where [¹⁸F]Galacto-RGD uptake was seen not only within but also adjacent to areas of infarction in the border zone. When only looking at segments with infarction (B), the inverse correlation was more pronounced, which shows that uptake of [¹⁸F]Galacto-RGD was not dominated by unspecific perfusion effects
