2021 Fiscal Year Research-status Report

低線量X線肺血流イメージングを用いた慢性血栓塞栓性肺高血圧症の新規診断法の確立

Research Project

Project/Area Number 20K16728
Research InstitutionKyushu University

Principal Investigator

山崎 誘三  九州大学, 大学病院, 助教 (00643347)

Project Period (FY) 2020-04-01 – 2023-03-31
Keywords胸部X線動態撮影 / 慢性血栓塞栓性肺高血圧症
Outline of Annual Research Achievements

本年度は主に症例の解析を行なった。CTEPH(慢性血栓塞栓性肺高血圧症), non-CTEPH症例の分別能を評価する検討を行ない、肺換気/血流シンチグラフィと比較し、感動、特異度、正診率などがどの程度であるかを読影実験を行った。代表的な症例を画像論文として、American Journal of Respiratory and Critical Care Medicineに投稿し、受理されている。 さらにCTEPHにおいて、肺血流の定性的、定量的評価の精度を検証するため、肺血流シンチグラフィと比較した。比較的良好な相関が得られ、手術前後の評価においても有用であった。また、病的状態を評価するため、健常者での正常値について、解析を行い、今後発表予定である。

Current Status of Research Progress
Current Status of Research Progress

2: Research has progressed on the whole more than it was originally planned.

Reason

本年度中に解析まで進め、論文作成までできているため。

Strategy for Future Research Activity

論文受理を目指して、投稿、改訂を行なっていく予定。

Causes of Carryover

COVID-19の影響で、学会がonline化され、出張費の使用がほぼなかったため。
