多层螺旋CT肺动脉造影在肺栓塞诊断中的应用进展

Application Progress of Multi-Slice Spiral CT Pulmonary Angiography in the Diagnosis of Pulmonary Embolism

摘要: 肺栓塞(Pulmonary Embolism, PE)是由内源性或外源性的栓子堵塞肺动脉主干或分支导致的肺循环障碍综合征。近年来，其发病率呈上升趋势。多层螺旋CT肺动脉造影(Multi-slice Spiral CT Pulmonary Angiography, MSCTPA)是一种无创性检查技术，在临床广泛应用，16层螺旋CT具有快速、薄层、分辨率高等优点，在诊断肺栓塞上发挥了重要作用。本文系统性地梳理了多层螺旋CT肺动脉造影的技术原理与分类、优势、技术进展、临床应用策略，对于指导临床医生，特别是基层或非专科医生合理选择检查、制定诊疗方案具有显著的教育和指导价值。文章综合了技术原理、临床实践和未来展望，为读者提供了关于该主题的全面概览。

Abstract: Pulmonary Embolism (PE) is a syndrome of pulmonary circulation disorder caused by endogenous or exogenous emboli blocking the main or branch of the pulmonary artery. In recent years, its incidence rate has been on the rise. Multi-slice Spiral CT Pulmonary Angiography (MSCTPA) is a non-invasive examination technique that is widely used in clinical practice. 16-slice spiral CT has the advantages of rapidity, thin slice, and high resolution, and has played an important role in the diagnosis of pulmonary embolism. This article systematically reviews the technical principles and classification, advantages, technological progress, and clinical application strategies of multi-slice spiral CT pulmonary angiography. It has significant educational and guiding value for guiding clinical doctors, especially grassroots or non-specialist doctors, to rationally select examinations and formulate treatment plans. The article integrates technical principles, clinical practice and future prospects, providing readers with a comprehensive overview of the topic.
