Cardiac Imaging Using Clinical 1.5 T MRI Scanners in a Murine Ischemia/Reperfusion Model

Table 1

Infarct size in mouse heart after I/R procedure. Infarct size measured in magnetic resonance imaging by LGE in magnetic resonance imaging and histology (24 h after reperfusion by TTC staining and 1 week after reperfusion by trichrome staining). No infarction was detected in sham-operated mice. Values shown as mean percentage of left ventricular area ± standard deviation. *Significant difference to 30 min ischemia operated mice, all 𝑃<.05.
