螺旋CT在诊断肺动脉栓塞中的临床应用

目的通过分析确诊肺动脉栓塞患者的螺旋CT影像,探讨螺旋CT在诊断肺动脉栓塞中的临床应用。方法回顾性分析经临床确诊的39例肺动脉栓塞患者的螺旋CT征象,观察栓塞的分布类型及各级肺动脉的显示率及图像质量。结果 39例肺动脉梗塞患者,共累计179支肺动脉或分支栓塞,其中混合型18例,周围型16例,中心型5例,其中包括肺动脉主干1支,左右肺动脉21支,左右肺叶动脉47支,左右肺段动脉67支,左右肺亚段肺动脉43支。结论 16排螺旋CT增强扫描具有安全、快速、无创及诊断准确的优点,可清晰显示栓子的形态及栓塞范围,在肺动脉栓塞中具有重要的临床应用价值。

Objective Through the analysis of patients diagnosed pulmonary embolism,plan to explore spiral CT imaging diagnostic pulmonary embolism spiral CT in the clinical application.Methods A retrospective analysis of 39 cases by clinical diagnosis of patients with pulmonary embolism,observe spiral CT signs the distribution types and levels embolization display rate and pulmonary image quality.Results 39 cases of pulmonary infarction patients,a pulmonary artery or branch cumulative 179 cases,including hybrids embolization 18 cases,peripheral l6 example,center,including 5 cases of pulmonary trunk 1 teams around 21 teams,pulmonary sequestration,about 47 teams around arteries,lung of the arteries,67 teams left lung and section pulmonary 43 pens.Conclusion 16 row helical CT scans have enhanced quickly,safely and accurately noninvasive and diagnosis advantage of clear display of the form and embolism embolus range,in pulmonary embolism has the important value of clinical application.
