Outline of Research at the Start

リンパ疾患はリンパ浮腫だけでも世界に1.7億人の患者がおり、癌患者の増加、手術の高度化などを背景に増加している。しかしリンパ系は殆どの疾患で診断も治療も十分に確立されていない。この主な原因はリンパ管の簡便な画像診断がなく、現在でも可視化が容易ではない事にある。従って、画像診断の進歩によるリンパ管の可視化と動態の解明が、これらの診療と研究を導くキーである。本研究では、先進的MRイメージングと独自のマルチモダリティアプローチにより、リンパ系の新規画像診断法の確立を目指す。リンパ管画像診断のレベルを押し上げ、より低侵襲で精密な治療へ展開する事で、リンパ管疾患に苦しむ多くの患者に福音をもたらしたい。

Outline of Final Research Achievements

This study aimed to establish advanced lymphatic imaging techniques using MR lymphangiography (MRL), photoacoustic imaging (PAI), and upright CT. We developed a novel MRL-based severity classification of lymphedema and published it in an international journal. This system characterizes patterns of dermal backflow and lymphatic visualization based on anatomical region and clinical stage, showing significant correlations with disease severity and duration. It enables a more detailed assessment of individual pathology and supports optimal treatment planning. We also established an improved robust MRL protocol with reduced artifacts and applied MR thoracic ductography to manage refractory lymphatic leakage. Furthermore, comparative analyses of MRL and PAI clarified their complementary roles. Quantitative evaluation of fat tissue changes related to lymphedema was also conducted. These efforts contributed to the standardization of diagnostic approaches in lymphatic disease management.

Academic Significance and Societal Importance of the Research Achievements

本研究は、従来は困難とされていたリンパ管の三次元的かつ高精度な可視化を実現し、MRリンパ管造影(MRL)や光音響イメージング(PAI)を用いた新たな画像診断と診断基準の確立、治療支援法の進歩に寄与した。学術的には、これらの画像技術に基づく客観的で再現性の高い評価手法を提示し、リンパ管疾患における画像診断と治療の進歩に貢献できたと考える。社会的には、従来の診断や治療が未発達もしくは困難であった、リンパ浮腫や難治性リンパ漏などの診療の質を向上させ、患者のQOL改善にも貢献できたと思われる。近年著しい発展を見せるリンパ管の診療や研究を推進する上でも、これらに寄与できる成果と考えられる。
