Description
6匹の幼若Sprague Dawleyラット(4〜5週齢、平均体重114g)に0.4μL/gの完全フロイントアジュバントを注射(ラット3匹には右膝、ラット3匹には右足首)することによって関節炎を誘導した。誘導の7日後に、励起及び信号受容の両方のために自己遮蔽グラジエント(40mT/m、150mT/m/ms)及び特注のデュアルチューン(1H/13C)直角位相コイル(φ=80mm)を備えたGE 3T スキャナーにより、13C MRSによって関節炎の関節を造影した。13C−1−ピルビン酸塩の100mM溶液0.5mLをDNP(15〜20%液体状態分極)によって過分極し、尾静脈から注射した。注射の20秒後に、FID CSIシーケンス(ボクセル=2.5×2.5×10mm、FOV=4×4cm)によって13C−1ピルビン酸塩及びその代謝産物の単一時点MRS解析を得た。2回目の過分極13C−ピルビン酸塩の注射の間、1D EPSIシーケンスによって時間分解造影を得た。関節におけるROI解析によってピルビン酸塩及び乳酸塩の平均信号強度を得て、正常及び関節炎の関節をT検定によって比較した。
