PET imaging with oxygen-15 indirectly measures blood flow to the brain. In this method, increased radioactivity signal indicates increased blood flow which is assumed to correlate with increased brain activity. Because of its 2-minute half-life, 15 O must be piped directly from a medical cyclotron for such … Zobraziť viac Positron emission tomography (PET) is a functional imaging technique that uses radioactive substances known as radiotracers to visualize and measure changes in metabolic processes, and in other Zobraziť viac PET scanning is non-invasive, but it does involve exposure to ionizing radiation. F-FDG, which is now the standard radiotracer used … Zobraziť viac The concept of emission and transmission tomography was introduced by David E. Kuhl, Luke Chapman and Roy Edwards in the late 1950s. Their work later led to the design and … Zobraziť viac The overall performance of PET systems can be evaluated by quality control tools such as the Jaszczak phantom. Zobraziť viac PET is both a medical and research tool used in pre-clinical and clinical settings.

[ F]FDG, as a glucose analog, is taken up by high-glucose-using cells such as brain, brown adipocytes, kidney, and cancer cells, where phosphorylation prevents the glucose from being released again from the cell, once it has been absorbed. The 2-hydroxyl group (–OH) in normal glucose is needed for further glycolysis (metabolism of glucose by splitting it), but [ F]FDG is missing this 2-hydroxyl. Thus, in common with its sister molecule 2-deoxy-D-glucose, FDG canno… dcu 公式インタビューブック
