脂肪肝(A)患者においてBGとしての肺集積が増加する可能性がある．Aが及ぼすF集積への影響と，遅延像(D)撮像による有効性を評価した．
2015年1月から8月までにHCC以外の癌患者のうち、肺を含むPET撮像を行った患者8名（男3名、女5名）を対象。
SUVはA患者で有意に非脂肪肝よりも低下した．
A患者では早期像のみでは肺の背景集積の増加により,病変が見落とされる可能性があるが，Dを撮像することで非脂肪肝と同様の画像を提供できる．A患者では積極的にDを撮像するとよいかもしれない．
Lung accumulation as Back ground may increase in patients with fatty liver (A). The influence on F accumulation by excerted on fatty liver and effectiveness by delayed image (D) imaging were evaluated.
For January to August, 2015,
8 patients (3 males and 5 females) who had PET imaging of lungs out of cancer patients except HCC were covered.
SUV was significantly lower in fatty liver patients than non-fatty liver.
In fatty liver patients, lesion may be overlooked due to an increase in accumulation of lung background only with early images, but by imaging D, it is possible to provide an image similar to non-fatty liver. For fatty liver patients, it may be better to positively image D.
