Figure 6From: An isolated perfused pig heart model for the development, validation and translation of novel cardiovascular magnetic resonance techniquesPerfusion 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.Back to article page
