PET/CT images of F-18 AlF-NOTA-BCP137 in patients with hepatocellular carcinoma (HCC) and immunofluorescence analysis of patient tissues. (A) F-18 AlF-NOTA-BCP137 PET/CT images before and after immunotherapy for patient 1 and patient 2. (B) F-18 AlF-NOTA-BCP137 PET/CT and MR images of patient 3 (left panels) after one cycle of immunotherapy. PET images showed higher uptake by tumor and spleen, and PET result was evaluated as positive; therefore, the patient was considered to be responder to treatment and underwent surgical resection. Representative images of hematoxylin and eosin (HE) staining and multiplex immunofluorescence of CD8 and CD137 (right panels) in HCC tumor and adjacent normal tissues of patient 3 after surgery. Nuclei were stained with 4′,6-diamidino-2-phenylindole. Primary tumors are indicated by white arrows, and increased thyroid uptake is indicated by red arrow in PET images.
