Multimodality imaging, as represented by its greatest exponent, PET/CT, has a firm place in the evaluation of a patient presenting with cancer. With 18F-FDG, PET/CT is rapidly becoming the key investigative tool for the staging and assessment of cancer recurrence. In the last 5 y, PET/CT has also gained widespread acceptance as a key tool used to demonstrate early response to intervention and t...
The greatest health problem in sub-Saharan Africa is the complex of HIV and TB. PET has been primarily developed to look at cancer but can PET be used for this major health problem. F-18FDG has a high sensitivity in TB but the pattern of uptake is not specific. Attempts to improve the specificity of F-18 FDG imaging in the context of TB by using dual time scanning has not proved useful. There i...
In the synthesis of 18F-FDG by the nucleophilic substitution method, 18O-H2O is usually used as target water. The target water should be recovered after synthesis and reused, because it is expensive, but recovered water contains impurities such as organic substances, and it must be purified before reuse. For this reason Sumitomo Heavy Industries, Ltd. developed an O-18 water purifier for elimin...

In fact, clinical features are not specific and structural imaging can be normal in a considerable number of cases. However, an early diagnosis is important as many forms of treatment are effective if started promptly. Even though recent guidelines do not recommend (18)F-FDG PET/CT for patient...
