衡宇 发自 凹非寺 量子位 | 公众号 QbitAI AI新进展，救命的那种。 现在， 只需做一次体检时常规的CT检查，再用AI分析，就有可能在癌症还没有露出明显症状之前——比如提前半年——把它揪出来 。 今天，国内与之相关的一项成果登上国际顶级期刊《自然·医学》 （Nature Medicine） ： 咱们普通人，往往都是闻癌色变。 众多癌症中，胃癌不仅是我国最常见的恶性肿瘤之一，且导致的死亡人数还特别庞大——每年约26万例，在所有恶性肿瘤中居于第三。 不过患上胃癌并不一定等于死神降临。 如果在早期发现并切除，5年生存率可达95%～99%，甚至有完全治愈的可能 。 然而，早期胃癌没有区别于普通胃炎的特异性症状，我国胃癌早期发现率长期徘徊在20%-30%之间。 现在医学界主流的胃癌早筛方法是"问卷+胃镜" ，也就是先填标准化风险评估问卷，然后根据问卷结果，让筛选出的高/中危人群做胃镜筛 查。 全球首个利用平扫CT识别早期胃癌的AI模型DAMO GRAPE 。 它首次突破了传统影像学的限制，实现了用非增强的普通CT识别胃癌的可能性。 实际操作中，DAMO GRAPE在全国20个中心近10万人的大规模临床研究证明 ...
