[MRI image analysis of 1,2-dichloroethane chronic toxic encephalopath].

OBJECTIVE

To study the MRI features of 1,2-dichloroethane Chronic Toxic Encephalopathy of 10 cases.

METHOD: 10 cases were examined by MRI, slice thickness 8 mm, layer from 2 mm, axial and coronal line scan, T1WI, T2WI, FLAIR imaging.

RESULTS

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.

CONCLUSION

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.
