| Outline of Final Research Achievements |
The purpose of this study is to develop the non-invasive method for detecting minimal cancer invasion and cancer stem-like cells using hyperspectral endoscopic and DNP-MRI redox (metabolic) imaging technologies.
The eraly diagnosis for minimal disseminated cancers is difficult by conventional MRI, because it is difficult to discriminate the density between small volume of malignant ascites and tissue water components at the early stage of cancer progression. We have herewith met in success to develop the analysis method using DNP-MRI that visualize a minimal volume of malignant ascites as a diagnosis marker for early stage of peritoneal dissemination. Hyperspectral imaging discriminated high vascular flow and low-oxigen concentration in subcutaneous tumors from the surrounding normal counterparts.
These results indicate the potential of DNP-MRI and hyperspectral endoscope imaging as an useful diagnosis modalities for minimal cancer invasion and dissemination.
