Dual-energy CT permits a variety of image reconstructions for the depiction and characterization of vascular disease. Techniques include visualization of low- and high-peak-kilovoltage spectra image datasets and also material-specific reconstructions combining both low- and high-peak-kilovoltage data.
This article focuses on four main vascular areas: the aorta, the major visceral, lower limb, and cervical arteries. For each territory, the current status, potential advantages, and limitations of these techniques are described.
双能 CT 允许对血管疾病进行多种图像重建，以进行描述和特征分析。技术包括可视化低和高峰千伏光谱数据集图像，以及结合低和高峰千伏数据的材料特异性重建。
本文主要关注四个主要的血管区域：主动脉、主要内脏、下肢和颈动脉。对于每个区域，描述了这些技术的现状、潜在优势和局限性。
