2、D患者臨床癥狀明顯改善,同時腦局部糖代謝也發(fā)生了明顯變化,雙側豆狀核,腦干(中腦、腦橋)、雙側頂枕部、運動前區(qū)(BA6)及扣帶回的腦代謝增加;前額葉底部、海馬的腦代謝減少(P<0.05)。結論:雙側STNDBS可能通過興奮STN軸突的方式,使軸突投射區(qū)域的基底節(jié)上行和下行通路代謝改善,并增加相應的額葉高級運動中樞的代謝,使PD患者臨床癥狀改善。FDGPET可能是為STN治療挑選合適病例的方法之一.關鍵詞帕金森病PET脫氧葡萄糖丘腦底核腦深部電刺激中國圖書資料分類法分類號EvaluationofdeepbrainstimulationtreatmentforParkinson'sdis
