We continue to lead in the synthesis of tracer RI for PET & SPECT scans. PET & SPECT scans demonstrate significant effects for the image diagnosis of tumors, cerebral infarctions and cardiovascular diseases. Tracer RIs, such as the 18F-FDG, which is used for identifying the position of cancer by accumulating at the cancer nidus, are essential for PET scans, which have been adopted by many medical institutions. The cyclotron systems for PET & SPECT provide radioactive isotopes, which are required for the manufacture of these tracer RIs, in a safe and stable manner.
