[Progress in the application of artificial intelligence in gastric cancer imaging].

Gastric cancer is a common malignant tumor of digestive tract, and its prognosis varies greatly with different stages of the tumor. In recent years, more and more evidence shows that artificial intelligence (AI) technology has excellent performance in imaging diagnostic applications, with remarkable diagnostic effects and broad prospects. AI not only improves the accuracy of diagnosis and staging of gastric cancer, but also has great application value in pathological assessment, adjuvant therapy and prognosis prediction. This article systematically reviews domestic and foreign literature to explore the application progress of AI in gastric cancer imaging.胃癌是常见的消化道恶性肿瘤，其预后与肿瘤分期密切相关。影像学检查在胃癌的临床诊断、分级分期、疗效评估及预后预测等方面发挥着重要作用。近年来，结合影像组学特征的人工智能技术，成为胃癌诊疗方面研究的热点。越来越多的研究证据表明，人工智能（AI）技术在影像学诊断应用中具有卓越表现并且前景广阔。AI不仅提高了胃癌诊断与分期的准确度，而且在胃癌的病理评估、辅助治疗和预后预测等方面均具有极大的应用价值。本文系统回顾国内外相关文献，综述AI在胃癌影像学中的应用进展。.
