脑卒中的CT诊断与鉴别诊断
CT Diagnosis and Differential Diagnosis of Cerebral Stroke

脑卒中是一种由于血管、血液及血流动力学异常引起脑部血液供应障碍，造成脑实质缺血与水肿，导致脑组织缺血性坏死或软化的一种急性脑血管疾病。随着我国人口老龄化的现象不断加剧，预计在未来十几年内，中风将持续影响居民健康，因此对脑卒中患者的早期诊断显得十分重要。随着影像技术的发展，影像学检查可以对卒中患者进行脑形态学和功能学综合诊断，在临床中仍以CT检查为首选的检查方法。本文通过总结缺血性脑卒中、出血性脑卒中等各型卒中的CT影像表现，进一步明确了各型脑卒中的诊断与鉴别诊断，为临床对脑卒中的早期诊断提供了一定的依据。
Cerebral Stroke is an acute cerebrovascular disease caused by abnormalities in blood vessels, blood flow, and hemodynamics, leading to cerebral ischemia and edema, resulting in ischemic necrosis or softening of brain tissue. With the increasing aging population in China, it is expected that stroke will continue to affect the health of residents in the next decade or so. Therefore, early diagnosis of stroke patients is very important. With the development of imaging technology, imaging examinations can be used for comprehensive diagnosis of brain morphology and function in stroke patients, and CT examination is still the preferred examination method in clinical practice. This article summarizes the CT imaging manifestations of various types of stroke in ischemic stroke and hemorrhagic stroke, further clarifies the diagnosis and differential diagnosis of each type of stroke, and provides a certain basis for early diagnosis of stroke in clinical practice.
