Tungsten is used as shielding material in radiation medicine. It always uses tungsten container when transporting fluorodeoxyglucose, whose high energy makes the fluoro-18 lead container unusable.

Fluorodeoxyglucose is a fluoro derivative of 2-deoxyglucose, usually referred to as 18F-FDG or FDG. FDG is most commonly used in positron emission tomography (PET) medical imaging equipment. After injecting FDG into the patient, the PET scanner can construct an image that reflects the distribution of the FDG in vivo. Then, the nuclear medicine physician or radiologist evaluates these images to make a diagnosis of various medical health conditions.

 

 

18F-FDG can be used to assess glucose metabolism in the heart, lungs, and brain. FDG-PET can be used for cancer diagnosis, staging and treatment monitoring, especially for Hodge's disease, non Hodge's lymphoma, colorectal cancer, breast cancer, melanoma, and lung cancer.

 

In addition, FDG-PET also has been used for the diagnosis of Alzheimer's disease. In the field of nuclear medicine, compound 18F-FDG, besides its important use in cardiology and neurology, it also exhibits cancer tissues that can be detected by conventional methods, or correct the misdiagnosis of these diseases.
