Comparison of ¹⁸F-FDG and ⁶⁸Ga-NOTA-MSA PET for detection of myocardial inflammation in myocarditis. A. The hotspots of myocardial inflammation colocalizes between the ¹⁸F-FDG and ⁶⁸Ga-NOTA-MSA PET scans in some animals. B-D. Different degree of ¹⁸F-FDG and ⁶⁸Ga-NOTA-MSA in spite of the similar degree of inflammatory cell infiltration. B. Similar degree of inflammatory cell infiltration on ED-1 immunostaining. C. Different degree of ¹⁸F-FDG uptake between the animals, despite similar degree of inflammatory cell infiltration. D. Similar degree of ⁶⁸Ga-NOTA-MSA uptake between the animals. SUV, standardized uptake value.
