Outline of Final Research Achievements

In the present study, we first developed the clinical amide proton transfer (APT) imaging sequence and optimized its parameters. We then evaluated its clinical usefulness in glioma patients. We employed Dixon method for B0 inhomogeneity correction in the 3D fast spin-echo sequence. The APT-weighted signals of tumor measured with the 3D-Dixon sequence was almost identical to those with single slice 2D sequence. With this condition, it was able to monitor the temporal progression of glioma, evaluate therapeutic response to anti-cancer drugs such as temozolomide and bevasizumab, and differentiate radiation induced necrosis from tumor progression. APT imaging can be a non-ivasive clinical tool to assess and monitor temporal changes in gliomas.

Academic Significance and Societal Importance of the Research Achievements

本研究では新しいMRIのコントラストを用いたAmide proton transfer (APT)イメージングの臨床使用に最適なシークエンスの開発を行い、その最適化をおこった。それを用いた臨床評価ではAPTイメージングはグリオーマの悪性度の進行の評価、化学療法後の治療効果判定および治療中のモニタリング、放射線治療による壊死と腫瘍進行との鑑別が可能であり、その臨床的有用性は高いと考えられた。
