被験者とMRIプロトコル
--------------------------------
https://openneuro.org/datasets/ds001378 からインポート
9名の[脊髄小脳失調症2型(SCA2)][1]患者と16名の年齢をマッチさせた健常対照者を、同じ1.5T MRIスキャナー(フィリップス・インテラ、オランダ、ベスト)で2回検査しました(SCA2患者は3.6±0.7年、対照者は3.3±1.0年の間隔)。取得した画像は以下の通りです。
- 矢状3D T1強調ターボグラディエントエコー画像[繰り返し時間
(TR) = 8.1 ms、エコー時間 (TE) = 3.7 ms、フリップ角 = 8°、反転
時間 = 764 ms、視野 (FOV) = 256 mm × 256 mm、マトリックスサイズ =
256 × 256、連続するスライス160枚、スライス厚 = 1 mm];
- シングルショットエコープラナー撮像シーケンスを用いた軸方向拡散強調画像(TR = 9394 ms、TE = 89 ms、FOV = 256 mm × 256 mm、
マトリックスサイズ = 128×128、スライス50枚、スライス厚 = 3 mm、ギャップなし、
励起回数 = 3)。拡散感度勾配は、b値0(b0画像)と1000 s/mm²を用いて、15の非共線かつ非共面の方向に印加しました。
