Outline of Final Research Achievements

This study was about high resolutional MRI that could be applied to clinical dentistry. We established a method of using CT and MRI fusion image, and we clarified its usefulness for detecting neuro-vascular bundles in mandible. We also clarified a non-enhancment MRI would be sufficient for this purpose. At final, we approached bifid mandibular canals and clarified their full pictures. These results were made well known via several presentations on the related society meetings and several original papers.

Academic Significance and Societal Importance of the Research Achievements

本研究では、これまで下顎管の描出にはCTが最適であるとの通念を打ち砕き、MRIの方がその検出率が高いことを明らかにした。さらに、CTとMRIの融合画像を用いることで、その3次元的な位置把握を可能にした。このことは、従来ではCTで下顎管が確認できない症例についても、その位置を特定することが可能にし、外科的処置を行う上で、より安全な医療を提供できる可能性が生まれたことを意味している。さらに、これまであまり全貌が明らかではなかった二分下顎管についての知見を提供することができた。今後も、本研究での手法を他部位に応用することで、画像診断の可能性を拡張できることを確信している。
