As of August 2008, Cancer Care Ontario reports that the current average incremental cost to perform a PET scan in the province is CA$1,000–1,200 per scan. This includes the cost of the radiopharmaceutical and a stipend for the physician reading the scan. [92] In the United States, a PET scan is estimated to be US$1500-$5000.
The only other obstacle to the wider use of PET-CT is the difficulty and cost of producing and transporting the radiopharmaceuticals used for PET imaging, which are usually extremely short-lived. For instance, the half-life of radioactive fluorine-18 (18 F) used to trace glucose metabolism (using fluorodeoxyglucose, FDG) is only
PET imaging uses radiotracers that target specific molecules or processes. For example, [18F] fluorodeoxyglucose (FDG) is commonly used to assess glucose metabolism, as cancer cells exhibit increased glucose uptake. Other radiotracers target specific receptors, enzymes, or transporters, allowing the evaluation of various physiological and ...

This is a list of positron emission tomography (PET) radiotracers. These are chemical compounds in which one or more atoms have been replaced by a short-lived, positron emitting radioisotope. Cardiology
In PET imaging, [18 F]FDG is primarily used for imaging tumors in oncology, where a static [18 F]FDG PET scan is performed and the tumor [18 F]FDG uptake is analyzed in terms of Standardized Uptake Value (SUV). FDG PET/CT can be used for the assessment of glucose metabolism in the heart and the brain.
Carbon-11 choline has also been used to detect tumors in the colon [7] and esophagus [8] and lung metastases. [9] Prostate cancer is another disease where carbon-11 choline PET imaging has found success. As with the brain, there is too much signal from the surrounding tissue, especially the bladder, to accurately measure tumor uptake with ...
The standardized uptake value (SUV) is a nuclear medicine term, used in positron emission tomography (PET) as well as in modern calibrated single photon emission tomography (SPECT) imaging for a semiquantitative analysis. [1] Its use is particularly common in the analysis of [18 F]fluorodeoxyglucose ([18 F]FDG) images of cancer patients.
