methionineが37検査、FDGが8検査であった。\n検査方法は薬剤投与後言ってのuptake時間の跡に、まずCT検査を施行し、その後同一ベッド上でPET検査を施行した。ＰＥＴは30分間のデータ収集を行った。CTとPETのfusion画像はコンピュータディスプレイ上に表示し、胸部、横隔膜、縦隔および腫瘍部などのPET集積とCT所見を比較した。画像の一致・不一致の評価は主に冠状断を用い、横隔膜、胸部、縦隔、腫瘍の各部に関して3段階(0:不一致、1:わずかに位置ずれ、3:よく一致）の評価を行った。結果は、不一致、わずかに位置ずれ、よく一致の割合がそれぞれ、横隔膜では8.9％、20%、71.1%、胸部では0%、2.2%、97.8%、縦隔では0%、2.2%、97.8%、腫瘍部では、3.2%、3.2%、93.6%で合った。横隔膜の不一致は前腹部近傍で出現する傾向が認められ、不一致の場合は全例でCTでの横隔膜秒酢つが尾側に位置する傾向を認めた。上〜中肺野領域の腫瘍部ではCTとPETは良好に一致していた。CT撮像時の呼吸管理下撮像を用いた本法は簡便で臨床上有用な方法であると判断された。","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名,
