- BACKGROUND: Integrated clinical whole-body PET/MR systems were introduced in 2010. In order to bring this technology into clinical usage, it is of great importance to compare the performance with the well-established PET/CT. The aim of this study was to evaluate PET performance, with focus on image

- While the first time-of-flight (TOF)-positron emission tomography (PET) systems were already built in the early 1980s, limited clinical studies were acquired on these scanners. PET was still a research tool, and the available TOF-PET systems were experimental. Due to a combination of low stopping po

- BACKGROUND: We have demonstrated recently that the tumor-to-blood standard uptake ratio (SUR) is superior to tumor standardized uptake value (SUV) as a surrogate of the metabolic uptake rate K m of fluorodeoxyglucose (FDG), overcoming several of the known shortcomings of the SUV approach: excellent

特徴・問題
- 吸収補正の違いによって差異が出る。
- CTを吸収補正に使用する方が外部線源を使用するより数%SUV値が高くなる。
- ソフト的にエネルギー換算しているCTを吸収補正に使用する方が、再現性や定量性には優れるが、真のSUV値という観点からすると疑問は残る。
- 部分容積効果によりサイズの小さなものは過小評価しうる。
