Assessment of infarct size via consecutive LGE-MRI and FDG-PET.

<p>(<b>A</b>) There was a good correlation between infarct size measured with LGE-MRI and FDG-PET. Acute riociguat treatment at reperfusion (blue) resulted in smaller infarcted areas than untreated controls (black). (<b>B</b>) Representative overlay images of LGE-MRI and FDG-PET of a mouse in the control group. Eepicardial and endocardial borders have been manually added on the LGE images for clarity. The infarct area, represented by hyperenhancement in the MRI images, matches an area of hypoenhancement on the PET.
