Figure 6 SPECT and PET Imaging of an Animal Injected With hNIS-Expressing Cells

(A to C) SPECT/computed tomography 24 h after cell injection. Red: technetium 99m uptake; green: thalium 201 uptake. White arrows point to signal from hNIS expressing rat cardiac-derived stem cells. (A) Transverse, (B) coronal, and (C) sagittal slice orientation. (D to F) PET of the same animal at 48 h after cell injection. Red: iodine 124 uptake; green: ammonia 13 uptake. White arrows point to signal from hNIS-expressing cells. (D) Transverse, (E) coronal, and (F) sagittal slice orientation. PET = positron emission tomography; other abbreviations as in Figure 3.
