Outline of Research at the Start

脳腫瘍にPET分子イメージングを応用し、腫瘍組織の増殖能と低酸素環境を評価する。新たな画像バイオマーカーとしてテクスチャ解析を計画し、腫瘍の形状や内部の特徴量といった性状を数値化する。脳腫瘍のPET検査で腫瘍増殖能と低酸素環境の病態評価を行い、従来の半定量的指標とテクスチャ解析指標を併用することで、予後予測、遺伝子変異予測、治療薬の反応性などの判断の向上ができるか否かを明らかにする。

Outline of Final Research Achievements

PET scans can provide a variety of metabolic information by using multiple imaging agents. Texture analysis can represent heterogeneity inside the tumor as a feature. We performed 18F-FLT and 18F-FMISO PET examinations in patients with brain tumors and also applied texture analysis. The results suggest the possibility of predicting IDH gene mutations and evaluating prognosis.

Academic Significance and Societal Importance of the Research Achievements

18F-FLT PETや18F-FMISO PETを用いて様々な病態評価を行う目的は腫瘍増殖能や低酸素環境を基に予後評価などに役立てる事である。PET画像での半定量的指標として主にSUVやT/N比などが用いられる。今回、テクスチャ解析をPET検査に応用することでSUV以外の新たな画像バイオマーカーとしての特徴量が算出でき、その有用性が示唆された。
