双源CT进行2种不同能量的X线同步扫描，可获得双能量图像，具有成像速度快，辐射剂量低，图像质量高的优点。双源CT进行冠状动脉成像，图像质量不再受患者心率过快、不规则以及屏气困难的影响，能获得可靠的冠状动脉图像，是目前无创性左室功能检查评价最具价值的检查方法之一。双源CT扫描时间缩短辐射剂量降低，有效克服部分患者移动伪影及呼吸伪影，适用于儿童患者及躁动患者的检查，为急性胸痛患者快速诊断提供安全有效手段。双源CT双能量虚拟平扫在头部、胸部、腹部疾病检查中已得到良好运用。双源CT在两种不同能量状态下的数据采集可对物质成分进行定性分析，拓宽了CT的应用范围，具有较好临床价值。

Dual source CT for 2 different energy X-ray scanning, can obtain the dual energy images, has fast imaging speed, low radiation dose, the advantages of high image quality. Dual source CT coronary artery imaging, image quality is not affected by the patient’s heart rate too fast, irregular and breath dififcult, can obtain the coronary artery image reliable;it is one of the current inspection method without evaluation and examination of the left ventricular function most value. Dual source CT scan can reduce the time of radiation dose, effectively overcome some patients moving artifact and respiratory artifacts, suitable for children patients and agitation of patients, to provide safe, effective method for the rapid diagnosis and emergency classiifcation of patients with acute chest pain. Dual energy CT virtual scan has been well used in the head, chest, abdominal disease examination. Dual source CT for qualitative analysis of components in two different energy state of the data acquisition, and widen the application range of CT, with good clinical application.
