脱髓鞘的活动性的病灶可以显示为弥散受限。
Active foci of demyelination may demonstrate restricted diffusion.
在我们的病例中，周边的弥散受限的薄壁环状影可能代表脱髓鞘病变的活动性边缘。
In our case, the thin peripheral rim of restricted diffusion may represent an active edge of demyelination.
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.
细胞毒性水肿和血脑屏障的破坏可能导致丘脑弥散受限及强化，这些很少见于基底节区。
Cytotoxic edema and blood brain barrier breakdown may be seen as decreased diffusion and enhancement, respectively, in thalami, and these manifestations may less commonly extend to basal ganglia.
很多累及胼胝体的弥散受限的局灶性病变也可以见于服用癫痫药物的癫痫患者以及低血糖患者。
More focal lesions with restricted diffusion involving the splenium can also be seen in patients with epilepsy receiving antiepileptic drugs and in the setting of hypoglycemia.
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.
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.
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.
ClaudeSirlin博士：正常组织的水分子弥散相对不受限制，而肿瘤组织的水分子弥散受到较大限制。
Dr Claude Sirlin: For simplicity normal tissues have relatively unrestricted water diffusion whereas water molecules in tumors are more restricted.
