Outline of Research at the Start

本研究の目的は、パーキンソン病の責任病巣である黒質緻密部のドパミン神経の変性脱落を定量的に評価可能な技術を開発し、その有用性を明らかにすることである。本研究では、Magnetic resonance imaging(MRI)を利用して、黒質の変性を定量的に評価可能な画像を得るための技術を開発する。さらに、この技術を健常者およびパーキンソン病患者に適用することによって、黒質の早期の変性を検出可能かどうか検証し、その有用性を明らかにする。

Outline of Final Research Achievements

A quantitative MR imaging technique was developed for the early detection of substantia nigra degeneration. The substantia nigra T1 values of patients with Parkinson's disease were significantly lower than those of normal subjects in the ventral region, suggesting its usefulness as an imaging biomarker for diagnosing Parkinson's disease. We also developed a spatially standardized atlas for selective assessment of vulnerable regions of substantia nigra, allowing quantitative assessment of relaxation time for each region. Baseline values of proton density, T1 and T2 values for each region, and age-related changes in relaxation times in each region were identified, allowing region-specific assessment of degeneration in a standardized space.

Academic Significance and Societal Importance of the Research Achievements

黒質の神経変性を早期に検出するための定量MRイメージング技術を開発した。パーキンソン病患者の黒質T1値は、腹側部で健常者よりも有意に低下したことから、黒質のT1値が早期のパーキンソン病診断となる可能性が示された。また、本研究で開発した黒質のアトラスは、脆弱性の高い領域を選択的に評価可能であり、得られたベースライン値を用いて各領域の緩和時間を詳細に変性評価が可能になった。今後、黒質に対する早期の変性評価への応用が期待できる。
