Outline of Research at the Start

画像の信号強度やゲノムなど複数のパラメータと病態との統計学的な関連性を各ボクセルまたは関心領域ごとに統合的に解析する手法として、radiomicsという概念が提唱されている。これまで、血行再建術によって回復した脳血流や大脳皮質神経受容体機能と運動機能との関係について、radiomicsにて明らかにした報告はない。
本研究では、血行再建術後の運動機能改善には、運動野および運動前野以外の領域の血流および神経受容体機能の改善も関与しているという仮説を立て、脳血流および神経受容体機能の術前後変化と最も関連する運動機能パラメータを全脳に渡るradiomics解析によって統計学的に明らかにすることとした。

Outline of Final Research Achievements

In this study, we aimed to clarify the mechanism of integrated motor control in the cerebrum by performing radiomics analysis (a comprehensive analysis that associates biological information of the lesion with a large number of quantitative features extracted from medical images) combining lower limb motor function and 123Iomazenil single photon emission computed tomography (IMZ-SPECT) with objective evaluation of upper limb motor function in patients with internal carotid artery stenosis. As a result of the study, it was revealed that Brodman areas 4 and 6, which indicate brain function localization, are related to improvement of upper limb motor function.

Academic Significance and Societal Importance of the Research Achievements

本研究の成果から、今後、123Iomazenil single photon emission computed tomography(IMZ-SPECT)の早期像・晩期像を利用することで、頚動脈内膜剥離術前後の運動機能改善が推測できるシステムの開発が期待できる。
