PET/CT images after ¹⁸F-FDG labeled CSC administration: Images of IM (A, B) and IC (C, D) administration of ¹⁸F-FDG-labeled CSC in pigs. A and C correspond to PET maximal intensity projection (MIP) images, showing the distribution of ¹⁸F-FDG activity over the entire body of the animals. B and D are sagittal sections of PET/CT images only in the heart area. In IM images, a spot-pattern uptake can be clearly observed over myocardial wall (h), whereas IC administration showed a diffuse uptake. ¹⁸F-FDG activity could also be clearly detected in bladder (b), kidneys (k) and lungs (l). Arrows point to lymph nodes with high ¹⁸F-FDG uptake
