Low-field MRI is less expensive and safer than high-field MRI. It is also possible to obtain high-sensitivity images using "hyperpolarization" of certain gases (eg 129Xe gas). In this study, we aimed to develop lung field imaging technology by low-field MRI of 0.3 T using hyperpolarized 129Xe gas, and observed chemical shifts in saline and porcine blood. As a result, it is expected to expand the possibility of high-sensitivity imaging diagnosis in a low magnetic field of 0.3 T and contribute to a new understanding of hyperpolarized 129Xe gas, and the practical application of these technologies is expected.本誌: 電気学会論文誌C（電子・情報・システム部門誌） Vol.144 No.4 （2024） 特集Ⅰ：量子・情報・エレクトロニクスの医療/ヘルスケア応用 特集Ⅱ：電子回路関連技術本誌掲載ページ: 296-300 p原稿種別: 論文／日本語電子版へのリンク: https://www.jstage.jst.go.jp/article/ieejeiss/144/4/144_296/_article/-char/ja/
