mri-guided disruption of the blood-brain barrier using transcranial focused ultrasound in a rat model

血液脳関門（BBB）の集束超音波（FUS）の中断は、BBB 1-5を回避するためのますます調査手法である。それは小さいサイズ6で約500 Daより分子に脳組織に血管系からの分子の通過を制限するようにBBBは、脳疾患の医薬治療への重要な障害である。 FUS誘導BBBの中断（BBBD）は一時的かつ可逆的4であり、高度にローカライズされていることBBBD誘導の化学的手段利点があります。 FUS誘導BBBDそれ以外の場合は十分な濃度の組織への成果物ではありません脳、上の治療薬の広い範囲の影響を調査するための手段を提供します。超音波パラメータの広い範囲がBBB 2,5,7中断することで成功を収めているが、正確なターゲティングに成功した混乱を確保するための実験手順で、いくつかの重要なステップがあります。この機能実装オールアウトラインはどのように重要な動物の準備と実験のマイクロバブル処理の手順に焦点を当てて、ラットモデルでBBBD誘導されるMRIガイド下FUSを実現しています。
