基于T1WI腦微結(jié)構(gòu)影像組學(xué)在診斷海馬硬化型顳葉癲癇中的研究摘要：

本研究旨在探討基于T1WI腦微結(jié)構(gòu)影像組學(xué)在診斷海馬硬化型顳葉癲癇中的應(yīng)用價值。選取了35例海馬硬化型顳葉癲癇患者以及30例健康對照者，采用磁共振成像（MRI）獲取腦微結(jié)構(gòu)影像。通過圖像處理和機器學(xué)習(xí)算法，將腦微結(jié)構(gòu)影像數(shù)據(jù)進行分析并建立分類模型。結(jié)果顯示，腦微結(jié)構(gòu)影像組學(xué)能夠?qū)崿F(xiàn)對于海馬硬化型顳葉癲癇的診斷，并且其診斷準確性較高，為90.5%。同時，本研究還探討了影響診斷準確性的因素，結(jié)果表明海馬大小和形態(tài)的改變是導(dǎo)致誤診的主要原因。因此，建議在診斷海馬硬化型顳葉癲癇時應(yīng)特別關(guān)注海馬的大小和形態(tài)變化情況。
