摘　　要：目的探讨螺旋CT对缺血性脑梗死与出血性脑梗死的鉴别诊断作用。方法选择75例脑梗死患者,其中缺血性脑梗死43例,出血性脑梗死32例,于临床症状出现6h^20d内均经颅脑CT平扫,分析其CT图像特征。结果缺血性脑梗死发病部位,10例位于额顶叶,15例位于颞顶叶,8例位于基底节,6例位于小脑,4例为一侧大面积脑梗死。出血性脑梗死发病部位,6例位于额顶叶,11例位于颞顶叶,6例位于基底节,8例位于小脑,3例为一侧大面积脑梗死。缺血性脑梗死患者CT征象包括脑回征、浮云征及假肿瘤征;出血性脑梗死患者CT表现分为非血肿型和血肿型。结论缺血性脑梗死与出血性脑梗死具有不同的CT表现,正确的鉴别诊断有助于指导临床治疗。Objective To investigate the value of spiral CT in the differential diagnosis of ischemic and hemorrhagic infarc- tion. Methods 75 cerebral infarction patients were selected, including 43 ischemic and 32 hemorrhagic cerebral infarction. CT scan were performed within 6h - 20d after appearance of clinical symptoms, and the CT image features were analyzed. Results Among sites of ischemic cerebral infarction, 10 cases were located in the frontal lobe, 5 cases in temporal lobel, 8 cases in the basal ganglia, 6 cases in the cerebellum, 4 cases with unilateral massive cerebral infarction. Among sites of hemorrhagic cerebral infarction, 6 cases in the frontal lobe, 11 cases in temporal lobe, 6 cases in the basal ganglia, 8 cases in cerebellum, 3 cases with massive cerebral infarction. CT findings in ischemic stroke include signs of gyrus, floating clouds and pseudotumor; CT findings in hemorrhagic stroke were divided into non-hematoma and hematoma infarction. Conclusion Ischemic stroke and hemorrhagic cerebral infarction have different CT findings, and the correct differential diagnosis can help guide clinical treat- ment.
