胃癌是最常见的消化系统恶性肿瘤，在临床中主要根据CT对胃癌进行分期及术前评估等。双能量CT成像是近年来出现的一种新型检查技术，与传统CT比较，不仅能有效地提高胃癌诊断的准确率和早期病灶的检出率，同时也在胃癌病理分型、分化程度及术前评估中具有独特的优势。就双能量CT的成像原理及其在胃癌临床应用中的价值进行综述。

Gastric cancer is the most common malignant tumor of digestive system and CT examination is mainly used for gastric cancer staging and preoperative evaluation in clinic. Dual-energy CT imaging technology is a newly emerged examination technique in recent years, it can not only effectively improve the diagnostic accuracy of gastric cancer and detection rate of early lesions but also show unique advantages in gastric cancer pathology classification, degree of differentiation and preoperative assessment compared with conventional CT. This review was focused on the principle of dual-energy CT and the clinical application value of dual-energy CT in gastric cancer.
