Outline of Final Research Achievements

When 5-aminolevulinic acid, a naturally occurring amino acid and a precursor of the heme synthesis pathway, is administered to a living body, porphyrin, an intermediate metabolite, is produced. In this study, we established a technique for detecting porphyrin-derived fluorescence in atherosclerotic plaques using a fluorescence vascular endoscopy system equipped with image analysis technology (multispectral imaging and spectral unmixing processing). Furthermore, as a new technological development related to endoscopic observation, we developed an endoscopic system that can easily observe the backside of target organs to ensure a sufficient field of view even in a deep and narrow surgical field.
