The Anatomic Study of Pulmonary Veins by Multi-slice Spiral CT / 实用放射学杂志

ABSTRACT

Objective To study the multi-slice spiral CT anatomy of pulmonary veins.Methods After accomplishing the scanning of coronary CT angiography in 120 cases with multi-slice spiral CT,the volume rendering and multi-planner reconstruction based on the original transverse images were performed.The pulmonary veins style according to the number of pulmonary-atrium ostium,pulmonary vein,common ostium and additional pulmonary vein were classified.The difference of sex in presence of the common ostium and additional pulmonary vein was analyzed statistically.Results The incidence of the common ostium and additional pulmonary vein was 22.5% and 15.8%,respectively,there was no difference in sex.The pulmonary veins included 4 typesstandard type(62.5%),common ostium type(21.7%),additional pulmonary vein type(15.0%),mixed variation type(0.8%).Conclusion Multi-slice spiral CT can accomplish the observation of pulmonary vein,which can provide anatomic informations for clinic.
