The faster scanning speed of 256-slice computed tomographic scanners has enabled electrocardiographic-gated imaging of the entire thoraco-abdominal aorta in several seconds. Electrocardiographic-gated acquisition allows for image reconstruction in any desired phase of the cardiac cycle, as well as dynamic assessment by looping the different reconstruction phases. We describe the application of 256-slice computed tomography in a patient with Marfan syndrome and acute type A aortic dissection. A comprehensive static and dynamic aorto-cardiac analysis was performed from a single scan, including the aortic dissection, aortic valve prosthesis, and coronary arteries.
256 层 CT 扫描仪的更快扫描速度使整个胸腹主动脉的心电图门控成像能够在几秒钟内完成。心电图门控采集允许在心脏周期的任何期望相位进行图像重建,并通过循环不同的重建相位进行动态评估。我们描述了 256 层 CT 在马凡综合征和急性 A 型主动脉夹层患者中的应用。从单次扫描中进行了全面的静态和动态主动脉心脏分析,包括主动脉夹层、主动脉瓣假体和冠状动脉。
