Group mean C-11 PBR28 SUVR maps of females with ASD (top) and female controls (middle). Statistical map from voxelwise comparison of C-11 PBR28 SUVR between groups, controlled for age and TSPO genotype, shows elevated regional TSPO levels relative to whole brain mean in the midcingulate cortex and splenium of the corpus callosum in ASD (N = 12) compared with controls (N = 10) (Z > 2.3, pcluster) (bottom). TSPO = translocator protein, ASD = autism spectrum disorder, CON = control, SUVR = standardized uptake value ratio, N = number. Image and caption courtesy of Neuropsychopharmacology.

F-18 FDG and Ga-68 FAPI-46 images of a 51-year-old woman with adenocarcinoma with lepidic growth pattern in right upper lobe. (A) Maximum-intensity-projection PET images. The lesion had F-18 FDG uptake below blood pool level but was strongly Ga-68 FAPI-46-positive. CT-guided biopsy led to pathologic diagnosis of adenocarcinoma, and the patient was treated by stereotactic body radiation therapy because of functional inoperability.
