这两种类型占CJD所有病例的85%。诊断该病主要依据临床特征、脑电图(EEG)波形特征和MRI表现。确定脑内是否有朊病毒蛋白则需要活检和尸检。 MRI是一种重要的检查手段,在变异型CJD和散发型CJD中表现不同。 sCJD在尾状核和豆状核的壳核处表现为双侧对称的T2高信号。在FLAIR和质子密度图像中也表现为高信号,弥散受限。

Creutzfeldt-Jakob disease (CJD) is a fatal brain disorder that is occur by human prion disease. The prion protein is an abnormal isoform of a cellular glycoprotein that is fast progressive, constantly fatal neurodegenerative disorder. MRI (Magnetic Resonance Imaging) is the correct choice to find ...
