Outline of Final Research Achievements

It is important that magnetic resonance (MR) imaging with fast acquisition needs to acquire the image data effectively in less time under control of deterioration of image quality. Dynamic MR imaging of the liver with the Compressed SENSE achieved one-half of acquisition time compared to conventional methods without deterioration of image quality, the result of which was supposed to be applied to patients with compromised breath-hold capacity, such as young children or critically ill adults. We demonstrated that MR cholangiopancreatography (MRCP) with the Compressed SENSE was comparable with conventions in one-quarter of acquisition time. Hepatobiliary phase imaging with the Compressed SENSE achieved double spatial resolution compared with conventional methods in a same acquisition time, which indicated improvement of diagnostic performance. Furthermore, we constructed a shortened abdominal MR imaging protocol, which abbreviated sequences of no importance for diagnostic imaging.

Academic Significance and Societal Importance of the Research Achievements

上腹部領域のMRI 撮像において、圧縮センシングとパラレルイメージングを相補的に併用した技術が臨床応用可能であることを示した。上腹部MRI撮像では複数回の呼吸停止や長い撮像時間が問題とされているが、我々の研究成果は患者の苦痛軽減や臨床現場における検査効率(スループット)改善に寄与するものと考えられる。
