| Outline of Final Research Achievements |
In the present study, a significantly strong correlation was found between the imaging parameter (Fis) of perfusion CT, which targeted the contrast accumulation in the intstitial space and relects tumor-associated stroma in this model, and stromal density quantified using immunohistochemistry; this finding supported our hypothesis that perfusion CT had the potential to depict a similar spatial distribution of tumor-associated stroma to that confirmed using histopathological analysis. In terms of the association between tumor hypoxia and tumor-associated stroma, FMISO uptake had a negative correlation with Fis and stromal density, as well as with vascular parameters. These results suggest that tumor hypoxia was complementarily localized to tumor-associated stroma and the vascular component.
