净结果是正常组织水分子弥散不受限制从而迅速丢失信号，看起来是暗的；而肿瘤看起来是明亮的。
The net result is that with normal tissues with their unrestricted diffusion with lost signals will look dark whilst tumors with their retained water signals will look bright.
基底节和皮质病变在T2和Flair序列上显示信号增高，弥散受限的原因尚未完全被理解。
The basal ganglia and cortical lesions show increased signal on T2 and FLAIR with persistent restricted diffusion. The cause of the restricted diffusion is not completely understood.
它们通常很小并且在T1和T2序列上高于脑脊液信号，弥散受限，可能会有强化。
They are usually small and will be hyperintense to CSF on T1 and T2 weighted imaging, show restricted diffusion, and may enhance with contrast.
由于固态的角蛋白表现为长t 1长t 2,ADC上是弥散受限的，Flair序列上呈混杂信号，这与蛛网膜囊肿是不同的。
Long T1 and T2 are due to keratin in solid crystalline state. Epidermoids have restricted ADC and complex FLAIR signal, unlike arachnoid cysts.
