病毒性脑炎指病毒侵犯脑实质,引起急、慢性炎症性疾病。引起病毒性脑炎的病毒种类众多,临床表现差异明显。病毒性脑炎的诊断仍依赖于实验室检查。MRI具有良好的组织对比分辨力,能清晰的显示病变本身及其周围的软组织变化情况,对于病毒性脑炎的诊断具有非常重要的作用,随着MRI技术不断发展,新的成像技术可以更好的显示病变,对病毒性脑炎诊断和治疗计划的制定具有很大帮助。本文综述了MRI技术在病毒性脑炎诊断中的应用。
Viral encephalitis refers to the virus invades the brain parenchyma, causing acute and chronic inflammatory diseases. Viral encephalitis caused by many types of viruses, significant differences in clinical manifestations. The diagnosis of viral encephalitis still depends on laboratory tests. MRI has good tissue contrast resolution, can clearly show the lesions themselves and surrounding soft tissue changes, for the diagnosis of viral encephalitis has a very important role, with the continuous development of MRI technology, new imaging technology can be better Of the display of lesions, viral encephalitis diagnosis and treatment plan to develop a great help. This review summarizes the application of MRI in the diagnosis of viral encephalitis.
