多层螺旋CT支气管动脉血管造影及临床应用

Multi-slice CT angiography of the bronchial arterial anatomy and its chinical application

多层螺旋CT血管造影对支气管动脉的解剖及病变的显示具有很大优势,它有多种后处理技术可应用于支气管动脉的显示。多平面重组(MPR)能对支气管动脉的开口、行程进行多方位观察,曲面重建(CPR)可显示支气管动脉的全程,最大密度投影(MIP)可显示较细小的血管,容积再现(VR)能给人以整体观。临床应用方面,本文参考文献分别从咯血、肺栓塞、中心型肺癌等方面分别阐述。

Multi-slice CT angiography could dearly visualize the bronchial arterial anatomy and lung disease. Multi-slice CT have many post-procession techniques appcied to the disphy of Bronchial artery. MPR could observe the origin and course on different angles.CPR could display the whole course. MIP may dealy show the small vessel. VR can make as a whole visually. This review summarizes the clinical using of multi-alice CT on hemoptysis, pulmonary embolism and central lung cancer et al.
