随着超声的发展,设备的不断更新,超声诊断胃癌的符合率越来越高。胃癌是我国最常见的恶性肿瘤之一,进展期胃癌病死率高,胃癌的预后与病期密切相关,早期诊断胃癌能提高胃癌患者的生存率。实时超声的应用,超声胃肠造影和超声内镜的问世,对小病灶的发现和病变范围的确定更为确切,进一步提高了胃癌的早期诊断率。超声诊断具有无痛苦、无创伤、间接快速等优点,成为胃癌筛选的重要检查方法之一。 With the development of ultrasound, the equipment is constantly updated, the coincidence rate of ultrasound diagnosis of gastric cancer is getting higher and higher. Gastric cancer is one of the most common malignant tumors in our country. The incidence of advanced gastric cancer is high. The prognosis of gastric cancer is closely related to the disease. Early diagnosis of gastric cancer can improve the survival rate of patients with gastric cancer. The application of real-time ultrasound, ultrasound gastrointestinal endoscopy and the advent of endoscopic ultrasound, the discovery of small lesions and the determination of the extent of lesions more precise, to further improve the early diagnosis of gastric cancer. Ultrasound has the advantages of painless, non-invasive, indirect and rapid, as one of the important screening methods for gastric cancer screening.
