摘要
多层螺旋CT(MSCT)扫描速度快、层厚薄,采用多种后处理技术,图像空间分辨率高。MSCT肺动脉造影被广泛应用于研究肺血管,其可从任意方向观察肺血管解剖结构,便于肺血管解剖研究;其可清晰显示肺栓塞的直接征象和间接征象,从而对肺栓塞准确诊断。该技术还可从多个方向观察肺肿瘤与肺血管关系,显示肿瘤供血动脉及肺血管的受侵情况;同时,对肺动脉瘤、肺海绵状血管瘤及肺隔离症异常肺血管的显示直观、清楚。
multi-slice CT(MSCT) scanning is more faster and thinner than routine CT, with varid postprocessing technique, high image space resolution can exhibit the lesions clearly. Pulmonary angiography has been used widely in study on blood vessel, by which we can easily observe anatomic structure of pulmonary bloodvessel at randora aspect and aquire direct and indirect signs of pulmonary embolism. By pulmonary angiography, the relationship between pulmonary tumor and bloedvessel can be deplayed clearly, as well as feeding artery and the state of bloedvessel invaded. In addition, we can observe pumonary artery anenurysm, angioma cavernosum and pulmonary sequestration directly and distinctly by pulmonary angiography.
