PET quantification of ⁶⁴Cu radioactivity and increased ⁶⁴Cu uptake by muscular tissue injured by electroporation. Abundant ⁶⁴Cu radioactivity was present in the liver, in contrast to low physiologic ⁶⁴Cu radioactivity in the brain and non-injured muscle. Increased ⁶⁴Cu uptake by injured muscular tissue reached peak at 2 hour post injection, which has decreased by 24 hour post injection, but still significantly higher than ⁶⁴Cu uptake by the muscular tissue with inflammation induced by LPS and low background ⁶⁴Cu uptake by the non-injured muscular tissue. h, hour; LPS, lipopolysaccharides; % ID/g, percentage of injected dose per gram.
