Outline of Final Research Achievements

3D Image-Guided Brachytherapy (3D IGBT) has been developed for the treatment planning of cervical cancer by obtaining 3D images such as MRI and CT with the applicator inserted during intracavitary irradiation. Based on the current situation in Japan where MRI imaging for each intracavitary irradiation is difficult, we established and clinically applied MRI/CT image based IGBT, which is based on MRI and CT imaging for the first time and CT only for the second time and thereafter.

Academic Significance and Societal Importance of the Research Achievements

アクセスの限られるMRを最大限に活用し、汎用性があり患者スループットの向上が見込めるCTと組み合わせることで、高精度なIGBTの普及が期待できる点が、本研究の学術的、社会的意義である。また、子宮頸癌は開発途上国で罹患数が多い疾患であり、本研究の意義は日本のみならず開発途上国へも波及するものと考えられる。
