目的分析新生儿缺氧缺血性脑病的CT、MRI表现及其诊断价值。方法 32例新生儿缺氧缺血性脑病患者的影像资料,其中17例作MRI扫描,15例作CT扫描,回顾性分析患儿MRI及CT表现。结果 MRI检查17例显示为脑肿胀、脑内斑点或小片状出血、或并蛛网膜下腔出血,以T1WI和DWI序列观察较清楚。CT检查15例,表现为脑肿胀和散发小斑点或小片状高密度急性出血灶。结论 CT和MRI均能及时发现病变,对脑损伤程度能作出客观评价,为治疗和推测预后提供重要的依据。熟悉MRI和CT的影像表现特征,对于提高诊断正确率,指导临床诊疗有重要意义。
Objective To analyze CT and MRI findings and their diagnostic value in neonatal hypoxic-ischemic encephalopathy. Methods Thirty - two neonates with hypoxic - ischemic encephalopathy were included in this study. MRI was performed in 17 of them and 15 in CT scan. MRI and CT findings of children were retrospectively analyzed. Results Seventeen cases of MRI examination showed brain swelling, intracerebral hemorrhage or subarachnoid hemorrhage. The results of T1WI and DWI were more clearly observed. CT examination in 15 cases, manifested as swelling of the brain and the distribution of small spots or small pieces of high-density acute hemorrhage. Conclusion Both CT and MRI can detect the lesions in time and make an objective evaluation of the degree of brain injury, providing an important basis for the treatment and prognosis. Familiar with the imaging features of MRI and CT, for improving the diagnostic accuracy, guiding the clinical diagnosis and treatment is of great significance.
