Abstract:Cerebrovascular disease is the leading cause of mortality and disability in China, and assessing the imaging diagnosis accurately, especially in patients with acute ischemic stroke (AIS), is of great importance in formulating treatment program and improving prognosis. Neuroimaging has been developing rapidly in recent years, and new techniques have emerged to help clinicians in assessing the infarct size, evaluating the ischemic penumbra, and identifying responsible vessels in patients with AIS, these measures provide useful information for individualized clinical treatment. In this paper, we briefly summarized the new technologies and applications of computerized tomography (CT) and magnetic resonance imaging (MRI) in the diagnosis and treatment of cerebrovascular diseases, in order to provide reference for clinical imaging applications in cerebrovascular diseases.
