肺动脉输送静脉血,由右心室发出,从主动脉前向左后方斜升,在主动脉弓的下方(约T4椎体下缘)分为左、右肺动脉,左肺动脉较短,右肺动脉较长。左、右肺动脉经肺门入肺后,随支气管的分支越分越细,最后形成包绕肺泡壁的毛细血管网,进行交换气体。 注:肺动脉是输送静脉血至肺的功能血管,营养肺的血管来自胸主动脉...
CT angiography vs angiogram CT angiography is a less invasive version of the traditional angiogram. The main difference between the two procedures is that while a standard angiogram involves a catheter being inserted into the artery and to the area being studied, a CT angiogram does not require ...

能谱CTPA碘基物质分离技术可更好地反映肺动脉栓塞状态下肺组织血流灌注状态,从而能通过检测碘灌注减低区发现肺栓塞区。 能谱CT不但能获得物质密度及其图像,还能获得单能量图像,并能根据所得到的能谱曲线计算出该病变或组织的有效原子序数。 总的来说传统的肺动脉CTA 只有在看到血管内栓子时才能确定为栓塞,而无法直...
