Figure 3 Dual Isotope SPECT/CT of an Animal Injected With hNIS-Expressing Cells
(Red) Technetium 99m uptake; (green) thallium 201 (201Tl) uptake. There is a clear intramyocardial region (yellow arrows) corresponding to the rat cardiac-derived stem cell injection site within a perfusion deficit. Noninfarcted myocardium appears green due to 201Tl uptake. The liver was also visualized due to uptake of 201Tl. (A) Transverse, (B) coronal, and (C) sagittal slice orientation. CT = computed tomography; hNIS = human sodium-iodide symporter; SPECT = single-photon emission computed tomography.
