胃癌是消化系统常见的一种恶性肿瘤,临床病死率达到35%[1]。胃癌患者的临床预后与病程长短、治疗方法等有密切关系,早诊断、早干预可提高5年生存率[2]。影像科研究者一直致力于研究如何发现早期胃癌,并对其进行准确分期。随着多层螺旋CT(MSCT)技术的成熟及其在临床各个领域的广泛应用,可通过薄层容积扫描采集大量数据信息,还可经三维重建技术清楚显示肿瘤病灶侵袭的部位、范围及其肿瘤病灶本
Gastric cancer is a common malignant tumor of digestive system, the clinical mortality rate reached 35% [1]. The clinical prognosis of patients with gastric cancer and duration of the disease, treatment methods are closely related to early diagnosis and early intervention can increase the 5-year survival rate [2]. Imaging researchers have been working on how to detect early gastric cancer and accurately staging it. With the development of multi-slice spiral CT (MSCT) technology and its wide application in various clinical fields, it is possible to acquire large amounts of data by thin-layer volume scanning and to clearly display the location, Tumor lesions of this
