Outline of Final Research Achievements

The use of MRI-guidance for biopsy has several advantages such as no radiation exposure and excellent soft tissue contrast. A high field (1.2T) open MRI system has a suitable design for biopsy procedures and high imaging capability. Thus, a clinical study was conducted to evaluate the feasibility of MRI-guided biopsy using this system. In this study, MRI-guided biopsy was feasible and safe for targets of various locations in 10 patients.

Academic Significance and Societal Importance of the Research Achievements

画像ガイド下針生検は、従来主に超音波やCTを用いて行われ、MRIガイド下針生検はそれに適した装置や機器の制約から広く普及するに至っていない。本研究において高磁場オープンMRI装置を用いたMRIガイド下針生検手技の実行性が確認されたことにより、今後より多数例での有用性の確認へと研究が発展することが期待され、将来的にMRIガイド下針生検の普及や、腫瘍の治療などのより高度な画像ガイド下手技への応用につながる可能性がある。
