摘要
胃癌的发病率和死亡率均居世界恶性肿瘤前列,目前增强CT是胃癌术前诊断与评估的主要手段,但其多基于形态学评估,无法进行定量分析.以能谱CT及CT灌注成像为代表的功能成像技术发展迅速,其具有多种精准定量参数,有望弥补常规CT的缺陷.本文对能谱CT及CT灌注成像的基础原理、其在胃癌诊断、病理分型、分级、分期的评估以及疗效预测等方面的研究展开综述,旨在提高CT功能成像在胃癌治疗前评估中的认识.
Abstract
Both morbidity and mortality of gastric cancer are in the front rank among malignant tumors.At present,enhanced CT is served as an important imaging method for preoperative diagnosis and assessment of gastric cancer,but it is mostly based on morphological evaluation and unable to perform quantitative analysis.The functional imaging technology represented by energy spectral CT and CT perfusion imaging has a variety of quantitative parameters,which is expected to make up for the shortcomings of conventional CT.The review introduces the basic principles of energy spectral CT and CT perfusion imaging,and summarizes their applications in the diagnosis,pathological classification,grading,staging and efficacy prediction of gastric cancer,aiming to improve the understanding of functional CT imaging for the pretreatment assessment in gastric cancer.
