Folate receptor β-targeted Positron emission tomography imaging of activated macrophages in experimental myocardial infarction
[<sup>18</sup>F]FOL PET detects expression of FR-β, a marker of activated macrophages after MI. FR-β expression peaks early and remains elevated up to 3 months post-MI. Early FR-β expression is associated with worsening of left ventricular systolic function.
