MRI analyses of brain lesion in canine distemper encephalitis

本研究的主题是犬瘟热脑炎脑损伤的MRI分析。犬瘟热脑炎急性期脑组织无明显变化；炎症作用和心室增大。这些结果表明，MRI不是诊断犬瘟热脑炎急性期的工具。另一方面，在犬瘟热脑炎的某些阶段，出现脑沟狭窄、侧脑室和第三脑室增大、侧脑室变圆等变化。这一阶段可能会出现严重的炎症。在脑实质无炎症、侧脑室无圆缩期，脑沟增大。这一发现可能表明犬瘟热脑炎的慢性期。最后，在本研究中，犬瘟热病毒抗体试验和抗原试验对犬瘟热脑炎的诊断无效。

The Theme of this research was MRI analyses of brain lesion in canine distemper encephalitis. In the acute phase of canine distemper encephalitis, there were no changes in the brain ; inflammatory effects and ventricular enlargement. These results revealed that MRI is not diagnostic tool in the acute phase of canine distemper encephalitis.On the other hand, in some phase of canine distemper encephalitis, there were changes that narrow brain ditch, enlargement of lateral and third ventricles and rounding of lateral ventricles. This phase may show heavy inflammation time.And, in the phase that there were no inflammation in brain parenchyma and no rounding in lateral ventricles, the brain ditches were enlarged. This findings may show the chronic period of the canine distemper encephalitis.Finally, in this study, the antibody test and the antigen test of canine distemper virus were not useful in the diagnosis of canine distemper encephalitis.
