Evaluation of Advanced Gastric Carcinoma with Monoenergetic Spectrum Curve of Dual-source Dual-energy Computed Tomography

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),
