Outline of Final Research Achievements

A hybrid PET/MR system has recently been developed that enables the acquisition of FDG-PET and MRI simultaneously, and precise image co-registration. We showed that the comprehensive assessment of soft-tissue tumors via multiparametric voxel-based analysis could facilitate the diagnosis of malignancy of soft-tissue tumors

Academic Significance and Societal Importance of the Research Achievements

本研究は複数の機能画像を同時に高精細に取得できるPET/MR装置ならではの手法である。また、本研究の手法は発展性が高く、脳腫瘍や頭頚部腫瘍といった他部位の腫瘍への応用、良悪性診断のみならず治療効果の判定や予測などにも応用が可能である。また用いる機能画像に関してもPETおよびMRIの両者で様々に拡張性があり、PET/MR装置のマルチ分子イメージング装置としての可能性を切り拓く研究であると言える。
