分析脑梗塞影像表现，总结其影像诊断依据，并发现有价值的早期征象。统计140例脑梗塞病人，利用影像学检查方法，对各期脑梗塞的影像表现及临床表现进行总结。结果：脑梗塞早期征像为豆状核轮廓模糊，大脑中动脉高密度征，脑沟消失、模糊；亚急性期征像为梗塞灶密度均匀降低，边界清楚，可有水肿及占位效应，重者可导致天幕下疝；慢性期征像为病灶出现模糊效应；恢复期梗塞病灶可仅留囊腔，一般小于原发梗塞病灶。结论：脑梗塞的影像学诊断能提高早期诊断率，对各期脑梗塞影像诊断明确，为临床早期诊断、早期治疗提供可靠依据。
Analysis of cerebral infarction imaging performance, summarize the basis of its diagnostic imaging, and found valuable early signs. Statistics of 140 cases of cerebral infarction patients, the use of imaging methods, the performance of various stages of cerebral infarction and clinical manifestations were summarized. Results: The early signs of cerebral infarction were asclerosis of bean nucleus, high density of middle cerebral artery syndrome, disappearance of sulci and vagueness. The signs of subacute phase were as follows: the densities of infarction were uniformly reduced, the boundaries were clear, edema and mass effect were possible, Severe cases can lead to hernia under the canopy; chronic symptoms like fuzzy effect of the lesion; convalescent infarct lesions may only leave the cyst, usually less than the primary infarct. Conclusion: The imaging diagnosis of cerebral infarction can improve the early diagnosis rate. The diagnosis of cerebral infarction images is clear, which can provide a reliable basis for the early diagnosis and early treatment.
