OBJECTIVE
Dual-energy CT (DECT) is an innovative imaging modality that allows superior detection of pulmonary embolism, enhanced detection of urate in gout, and improved assessment of metal prostheses when compared with conventional CT.
CONCLUSION
The primary aim of this review is to describe these DECT protocols and compare each to its respective diagnostic reference standards. Moreover, this review will describe how to recognize, reduce, and eliminate DECT artifacts, thereby maximizing its diagnostic capabilities.
目的
与传统CT相比，双能CT（DECT）是一种创新的成像方式，能够更出色地检测肺栓塞，增强痛风中尿酸盐的检测，并改善对金属假体的评估。
结论
本综述的主要目的是描述这些双能CT方案，并将每种方案与其各自的诊断参考标准进行比较。此外，本综述将描述如何识别、减少和消除双能CT伪影，从而最大限度地提高其诊断能力。
