Outline of Final Research Achievements |
This study revealed that the extracellular volume fraction (ECV) correlates with the histological pancreatic fibrosis fraction. Moreover, ECV values were shown to be higher in the pancreatic cancer group. Previous reports have indicated that patients with pancreatic cancer tend to have increased pancreatic fibrosis, suggesting that ECV increases due to the fibrotic changes in the pancreas. Furthermore, the results of the multivariate analysis demonstrated that ECV is an independent determinant of the presence of pancreatic cancer.

Academic Significance and Societal Importance of the Research Achievements |
この研究では、造影CTから算出される細胞外容積分画(ECV)を用いて、膵臓の線維化の程度を非侵襲的に評価することができることが明らかになりました。さらに、ECVは膵臓癌患者で高値を示し、膵臓癌の独立した危険因子であることが示されました。ECVは、膵臓の線維化の進行を反映するイメージングバイオマーカーであり、膵臓癌の発生を予測するのに役立つ可能性があります。本研究の成果は、膵臓癌の早期発見や予防に貢献し、膵臓癌による死亡率の低下につながることが期待されます。
