Outline of Research at the Start

大血管転位症、修正大血管転位症、右室型単心室などの、右心室が体循環を担う先天性の
複雑心奇形では、体循環による経年的な高負荷によって右心室がリモデリングする。リモデリングは重篤な右心不全や同期性障害、致死性の不整脈などを引き起こし、やがては成人期に手術や心移植が必要となる。心臓再同期療法(CRT)は、成人期の複雑心奇形に対する有効な治療法として期待されているが、体循環右室に対するCRTの適応を決定するための臨床的な指標は確立されていない。本研究では独自に開発したシネMRI解析による体循環右室のリモデリング評価の、CRTの効果予測への有用性を明らかにし、新たな画像診断指標としての確立を目指す。

Outline of Final Research Achievements

The purpose of this study was to establish the usefulness of systemic circulation right ventricular remodeling analysis using magnetic resonance imaging (MRI) in predicting CRT effects. We have developed computer image analysis methods to achieve our goals, and have applied these methods to clinical research.
As a result, we have filed a patent application for a method that automatically reconstructs radially long-axis cine MRI from general short-axis images and automatically calculates right ventricular volume and three-dimensional strain. Furthermore, this technology has been packaged as software that operates in a general-purpose computer language, making it widely applicable. A clinical study applying this technology was published in an international journal.

Academic Significance and Societal Importance of the Research Achievements

本研究では一般的な短軸像の磁気共鳴画像から、自動的な右心室の画像解析法を開発した。従来、心機能画像解析は左心室に焦点が当てられていたが、近年、右心室も注目されるようになった。本手法は従来の画像検査法を変更する必要のない、高精度な右心室の後解析技術である。また、CTやPETなどの分子イメージングにも応用可能な汎用解析ソフトウェアを構築できたことは、右室疾患のさらなる病態解明や適切な治療介入時期の決定について、多施設研究によるエビデンス蓄積の加速が期待できる。さらに、開発手法の有用性を明らかにした臨床研究は、いずれも国際誌に掲載されており、我が国を中心とした国際共同研究への発展も期待できる。
