Application of CT Angiography in the Diagnosis of Acute Cerebrovascular Disease in Neurology

Abstract

This article explores the application and value of CT angiography in the diagnosis of acute cerebrovascular disease in neurology. We selected 260 patients in our hospital as the research object, analyzed their data in detail, and then used the spiral CT scan to obtain the most original image. According to the projection technology with the strongest intensity and the scanned image, a three-dimensional image was formed on the surface. The images were studied and the results were compared with the results of postoperative and DSA techniques to finally evaluate the value of CTA technology in the diagnosis of cerebrovascular diseases. A retrospective analysis and study of angiographic results of 260 patients with ischemic cerebrovascular disease who underwent digital silhouette angiography (DSA). According to the age of patients, patients can be divided into three groups: young group, middle-aged group and elderly group, aged 18–45 years old, 45–60 years old, 60 years old or older. According to the classification of ischemic cerebrovascular disease, we can divide 260 patients into cerebral infarction group and transient ischemic attack group. The calculation of stenosis rate is based on the research methods of symptomatic carotid endarterectomy abroad. The rate of detection of stenoses in 8 patients with TIA was 87%, and the rate of detection in 30 patients with cerebral infarction was 96%. The rate of aneurysms detected in the diagnosis of SAH is 83%. The diagnosis of cerebrovascular disease in the etiology and treatment of CTA in neurology department has a statistically significant difference in the ratio of confirmed diagnosis and positive rate of protection (P >0.05). Finally, we conclude that CT angiography is widely used in the diagnosis of acute cerebrovascular disease in neurology, and its therapeutic effect is quite significant, which is worthy of promotion in clinical diagnosis and treatment.
