18F-FHBG imaging and uptake analysis of BMSCs in a rat model of MI. (A) Transverse 18F-FHBG microPET/CT images of BMSCs (red arrows) in the transplant region 4, 17, 31, and 46 days after treatment. (B) Quantification of 18F-FHBG uptake in infarcted myocardium (% ID/g). G4, untransfected-BMSC-treated MI model. *P < 0.05 vs. G3, transfected-BMSC-treated MI model.
