99mTc-SER-4 nanoSPECT/CT imaging of Sn+ macrophages in heterotopic cardiac transplant model. Representative maximum intensity projection nanoSPECT/CT images of recipients with either a allogeneic or b syngeneic heart graft imaged 3 h post injection with 99mTc-SER-4. CT, SPECT and fused images from coronal (c, d, e, respectively) and transversal (f, g, h, respectively) planes are also shown. Arrows indicate site of abdominal cardiac transplant with uptake of tracer in allogeneic heart graft that are absent in the syngeneic heart graft model
