目的探讨成人脑白质病的影像学特征,为临床诊断和治疗提供可靠依据。方法对经临床证实的57例脑白质病影像学表现进行总结分析。结果血管性脱髓鞘39例,硬化性脱髓鞘6例,感染性脱髓鞘5例,中毒性脱髓鞘4例,脑白质营养不良性脱髓鞘3例。CT表现为脑白质内多发斑片状低密度区,MRI表现为脑白质内多发长T_2信号。结论MRI较CT能更清晰地显示脑白质异常,准确地反映病理改变特点,有助于进一步提高对脑白质病变的诊断水平。
Objective To investigate the imaging features of adult white matter disease and provide a reliable basis for clinical diagnosis and treatment. Methods The clinical manifestations of 57 cases of white matter disease imaging findings were analyzed. Results Vascular demyelination in 39 cases, sclerosing demyelination in 6 cases, infectious demyelination in 5 cases, toxic demyelination in 4 cases, leukodystrophy demyelination in 3 cases. CT showed multiple plaque-like low density area of the white matter, MRI showed multiple prolonged T 2 signal in the white matter. Conclusion MRI can show the white matter abnormality more clearly than CT, accurately reflect the characteristics of pathological changes, and help to further improve the diagnosis of white matter lesions.
