超声在胃癌检查中的临床应用

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。

The Clinical Application of Ultrasonography for Gastric Carcinoma

With the development of ultrasonic technology and the upgrading of ultrasonic device, the coincidence rate for detecting gastric cancer by using ultrasonic is higher and higher. Gastric cancer is one of the most common cancers in the world, especially in China, the advanced gastric cancer has a high mortality, and the prognosis is closely relative with illness stage, and the early diagnosis can improve the survival rate of GC patients. With the application of real-time ultrasound, ultrasonic gastrointestinal contras and endoscopic uhrasonography, the discovering of small focuses and the detecting of extent of disease are more accurate than before,which helps improve the diagnostic rate of gastric cancer in its early stage. With its advantage of no pain, no wound and rapidness, ultrasonic diagnosis has become one of the most important detecting ways for gastric cancer screening.
