摘要:

GASTRIC cancer is one of the most frequently diagnosed cancers and leading causes of cancer-related deaths. Computed tomography (CT) is routinely used to observe the tumor location, size, invasion, and metastasis, which are necessary for tumor staging and therefore treatment planning. With the recently introduced dual-source dual-energy CT (DECT), different kevS images could be obtained, the feature of which depending on the attenuation coefficient of the scanned tissue. We investigated spectrum characteristics of the curve of normal gastric tissue and those with gastric cancer, normal fat and invased fat, metastatic lymph nodes in DECT.
