ADH1A and neoplasm: As shown in Figure 7, micro-PET imaging of the SW480 tumor-bearing nude mouse model 60 min after injecting [18F]AlF-NOTA-ADH-1 revealed high radioactive uptake in the tumor with a tumor/muscle ratio of 1.443±0.121, T/Bone of 1.903±0.273, and T/Lung of 3.359±2.998, unlabeled ADH-1 inhibitors can significantly reduce the T/NT ratios, too.
