Standardized Uptake Value (SUV) is universally used in routine clinical practice. It is used as a parameter of the semi-quantitative in FDG - PET analysis. The SUV provides a determination of activity in a defined region of interest (ROI) normalized to the patient’s body weight and administered dose.
For SUV calculations, enter the following into the site’s computer: Use the patient dose previously selected from the phantom dose chart on page 10. DO NOT use the value of dose B. Use 70 kg (154 pounds) as the patient’s weight. Use the ROI data obtained for the minimum (min.), maximum (max.) and mean SUV values to complete tables 1 & 2 below.
20 wrz 2023 · Standardized uptake values (SUVs) of normal organs were evaluated by 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography and computed tomography (PET-CT) scanning.
Quantitative 18F-FDG PET is increasingly being recognized as an important tool for diagnosis, determination of prognosis, and response monitoring in oncology. However, PET quantification with, for example, standardized uptake values (SUVs) is affected by many technical and physiologic factors.
7 paź 2023 · The standardized uptake value (SUV) applies to PET imaging of tumors and typically uses the radioligand F 18 -2-fluoro-2-deoxy-D-glucose (FDG). The concentration of F 18 activity reflects glucose metabolism which is increased in tumor cells and inflammation.
A more physiologically meaningful measure from FDG PET images is the glucose metabolic rate (GMR) of a tissue. GMR is a more complex calculation than the SUV, and there is mixed evidence as to which SUV calculation method correlates best with GMR.
