To study the MRI features of 1,2-dichloroethane Chronic Toxic Encephalopathy of 10 cases.
10 cases were examined by MRI, slice thickness 8 mm, layer from 2 mm, axial and coronal line scan, T1WI, T2WI, FLAIR imaging.
10 cases show varying degrees of abnormal signal of white matters, low signal intensity on T1WI, high signal intensity on T2WI and FLAIR. MRI could also show extensive abnormal signal in cerebral white matter although the toxic manifestation is mild to moderate. Therefore the symptoms and the shows of MRI could be inconsistent.
Combined with a history of exposure, the show of varying degrees of abnormal signal of white matter in 1,2-dichloroethane Chronic Toxic Encephalopathy cases are characteristic.
研究10例1,2 - 二氯乙烷慢性中毒性脑病的MRI特征。
对10例患者进行MRI检查，层厚8mm，层间距2mm，行轴位及冠状位扫描，采用T1WI、T2WI、FLAIR序列成像。
10例患者均显示不同程度的白质异常信号，T1WI呈低信号，T2WI及FLAIR呈高信号。即使中毒表现为轻至中度，MRI也可显示脑白质广泛异常信号。因此，症状与MRI表现可能不一致。
结合接触史，1,2 - 二氯乙烷慢性中毒性脑病患者出现不同程度的白质异常信号具有特征性。
