image作成の方法とその有用性は多く検討されている。その最先端の一つがCT付きPET装置(PET-CT)として簡便に臨床利用できるようになった。我々は頭頸部領域の診断においてもPET-CTによって得られる解剖学的画像と機能画像の正確なfusion imageが有用であると期待している。しかし頭頚部領域は構造が複雑で診断や治療方針の検討に時としてMRIがCTに比べて有用と考えられ、PETとMRIのfusion imageが望まれる可能性がある。この観点から、今回PET-CTを利用したPETとMRIの画像重ね合わせ法を検討した。\n　対象は頭頸部腫瘍症例で検討した。使用したPET-CTはシーメンス社のBiographで11C-メチオニンを投与して検査を施行した。MRIはT1像を使用した。画像重ね合わせ処理にはDr.View LINAX版を使用した。手順は、?PET-CTで得られたCTとMRIをfusion し、?得られたfusion image のCTをPET imageと置換した。これによってPET-MRI fusion imageを得た。本法により多くの症例で比較的容易に正確なPETとMRI fusion imageを得ることができた。しかし一部の症例でfittingの解が得られない(重ね合わせ不成功)ものがあった。原因としてCTの撮影範囲と比較してMRIの撮像範囲が極端に狭いことや、MRIとPET-CTの撮影時の頭部角度が著しく違うなどの原因が考えられた。","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名,
