The use of dual-energy computed tomography (CT) allows for reconstruction of energy- and material-specific image series. The combination of low-energy monochromatic images, iodine maps, and virtual unenhanced images can improve lesion detection and disease characterization in the gastrointestinal tract in comparison with single-energy CT.
双能计算机断层扫描（CT）的应用能够重建特定能量和物质的图像序列。与单能CT相比，低能量单色图像、碘图和虚拟平扫图像相结合可提高胃肠道病变的检测及疾病特征的显示。
