PET/CT imaging of mouse muscular injury induced by electroporation at 2 hours after injection of ⁶⁴CuCl₂ as a radiotracer. A. Increased ⁶⁴Cu uptake by the injured muscular tissue in mice subjected to electroporation on left leg was visualized on PET/CT images, in contrast to low ⁶⁴Cu uptake in the muscular tissue of contralateral right leg with inflammation induced by LPS injection. B. Low background ⁶⁴Cu radioactivity in the muscular tissue of bilateral legs of normal control mouse. LPS, lipopolysaccharides; R, right; L, left; % ID/g, percentage of injected dose per gram.
