| Outline of Final Research Achievements |
By our original image processing method, maps of 1) quantitative tumor blood flow, 2) semi-quantitative tumor progression rate, 3) semi-quantitative tumor hypoxia can be successfully obtained using non-invasive diffusion and perfusion weighted MR imaging. For the investigation of clinical usefulness, values of these maps in pretreatment and early treatment period was correlated to the short term result of the non-surgical treatment. Percentage change between pretreatment and early treatment period in tumor progression rate was detected to have significant correlation in short term result. From this result, the map of tumor progression rate we developed can be used for the one of prognostic factor, in addition, for the further adjustment of treatment regimen and the determination of follow-up strategy.
