Perfusion territory and Size of Infarction. The perfusion territory of the RCA was mapped in the 3 Tesla scanner by first pass perfusion with direct injection of the contrast agent into the RCA (central image). The perfusion territory was 96 g (36% of left ventricular myocardial mass). Then the RCA was occluded for 180 minutes. Late gadolinium enhancement (LGE, image on the right) resulted in 95 g myocardial infarction (36% of LV mass). The close agreement of LGE and selective RCA perfusion highlights the almost complete absence of collaterals in pigs. A Anatomic reference plane (midmyocardial slice). B k-t SENSE selective RCA first pass perfusion. C LGE image after 180 minutes of RCA occlusion. The images have been segmented to improve visibility.
