WebbPurpose: In this study, we measured test-retest reproducibility of SUV measurements under clinical practice conditions and recorded recognized deviations from protocol … 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. Its use is particularly common in the analysis of [ F]fluorodeoxyglucose ([ F]FDG) … Visa mer While this equation looks simple, there are a number of points that need to be discussed, such as (1) the origin of cimg data, (2) the origin of cinj data, (3) time, and (4) units. Image Visa mer The SUV can be significantly affected among other things by image noise, low image resolution and/or user biased ROI selection. For the semiquantitative analysis of [ F]FDG … Visa mer As of 2007, the SUV concept had only begun to be tested for other radiotracers such as fluorothymidine F-18 ([ F]FLT) and conclusions on its usefulness and robustness in these … Visa mer The ratio of the SUV data from two different regions within the same PET image (i.e. from a target and a reference region) is commonly abbreviated SUVR. An example is the ratio of regional Pittsburgh compound B PET signal intensity to the … Visa mer • Functional imaging • Medical imaging • Positron emission tomography • Fluorodeoxyglucose • Multi-compartment model Visa mer
