Fig. 2From: The chemical tool-kit for molecular imaging with radionuclides in the age of targeted and immune therapyImaging the sodium-iodide symporter. Top: Synthetic radiolabelled substrates of the sodium-iodide symporter hNIS used for radionuclide imaging. Left to right: [99mTc]pertechnetate; [18F]tetrafluoroborate; [18F]fluorosulfate; [18F]hexafluorophosphate. Bottom: Images show [18F]tetrafluoroborate PET images of healthy mouse (left), human with unresected thyroid cancer (centre) and, in the same subject, enlarged coronal section of thyroid region showing “cold” regionBack to article page
