Dual energy CT (DECT)with image acquisition at two different photon X-ray levels allows the characterization of a specific tissue or material/elements, the extrapolation of virtual unenhanced and monoenergetic images, and the quantification of iodine uptake; such special capabilities make the DECT the perfect technique to support oncological imaging for tumor detection and characterization and treatment monitoring, while concurrently reducing the dose of radiation and iodine and improving the metal artifact reduction. Even though its potential in the field of oncology has not been fully explored yet, DECT is already widely used today thanks to the availability of different CT technologies, such as dual-source, single-source rapid-switching, single-source sequential, single-source twin-beam and dual-layer technologies. Moreover DECT technology represents the future of the imaging innovation and it is subject to ongoing development that increase according its clinical potentiality, in particular in the field of oncology. This review points out recent state-of-the-art in DECT applications in gland tumors, with special focus on its potential uses in the field of oncological imaging of endocrine and exocrine glands.
双能CT（DECT）在两个不同的光子X射线水平进行图像采集，能够对特定组织或物质/元素进行特征描述，推断出虚拟平扫图像和单能量图像，并对碘摄取进行定量分析；这些特殊功能使DECT成为支持肿瘤成像以进行肿瘤检测、特征描述和治疗监测的理想技术，同时减少辐射剂量和碘用量，并改善金属伪影的减少。尽管其在肿瘤学领域的潜力尚未得到充分探索，但由于不同CT技术的可用性，如双源、单源快速切换、单源序列、单源双束和双层技术，DECT如今已被广泛应用。此外，DECT技术代表了成像创新的未来，并且根据其临床潜力不断发展，特别是在肿瘤学领域。本综述指出了DECT在腺体肿瘤应用中的最新技术水平，特别关注其在内分泌和外分泌腺肿瘤成像领域的潜在用途。
