凤凰网科技讯 8月24日，阿里巴巴达摩院联合中国医科大学附属盛京医院等机构研发出肝癌诊断AI模型“DAMO LiON”，可通过CT影像识别微小的肝脏癌变病灶。    The government of Venezuela is set to offer stakes in the state-owned Banco de Venezuela and telecom service provider CANTV in the coming weeks, it’s being reported.,Announcing the Banco de Venezuela public offering at a news conference in June, Vice President Delcy Rodriguez said the move would “give impetus to the national stock market” and “open the doors” of the enterprises “to national and international investors in local currency or foreign currency.”,“I think an important time has come for the Venezuelan Stock Market,” she said, stressing that while Venezuelans are “taking the first step with the Bank of Venezuela… the telecommunications company CANTV is coming soon.”,The public offering is the latest in a series of moves by authorities in the Caribbean nation to correct the course of their ailing economy. In late July, Venezuelan President Nicolas Maduro signed a law designating a number of Special Economic Zones in the country, with an eye towards ultimately transcending “the oil rentier model.”,Venezuela has been plagued for years by shortages, extreme inflation, and other serious issues caused in large part by Washington’s unilateral sanctions regime aimed at crippling the country’s economy.,To make matters worse, last week, the British Supreme Court ruled that approximately $2 billion in Venezuelan gold that’s currently being held in the Bank of England belongs to opposition leader Juan Guaido, rather than the elected government.,Maduro’s administration has indicated it will appeal the decision, but it seems unlikely that authorities in Caracas will prevail, especially given the UK’s extensive history of plotting against the Venezuelan government.,While intermittent power outages continue to interfere with oil exports, there are growing signs that Venezuela may have finally turned the corner financially and could soon stand on its own feet once again. Earlier this year, the United Nations Economic Commission for Latin America and the Caribbean forecast that the economy will grow by 5.0% this year – the highest in all of South America.,The normalization of ties with Colombia’s incoming Gustavo Petro administration will also provide ample opportunities for increased income and reduced military expenditures. Business groups on both sides of the Colombia-Venezuela border say its planned reopening – which could come as soon as this week – should provide around $1.2 billion in trade by the end of the year.。

二 | 在两个月的真实世界前瞻临床试验中，该AI模型发现了15例原本被遗漏的恶性肿瘤，绝大部分为1厘米左右的病灶，帮助患者得到及时的手术或药物治疗。相关论文登上国际顶级学术期刊《自然•医学》（Nature Medicine）。据官方介绍，“DAMO LiON”模型作为“AI安全员”协助医生阅片，既能精准识别原发性肝癌，更擅长揪出容易被忽视的肝转移。

三 | 实验结果显示，AI模型识别出恶性肿瘤的准确率高于放射科医生。当医生用AI模型协助阅片，用时减少了27%，而对恶性肿瘤的敏感性更提高了11.5%，有效减少漏诊；在AI 协助下，初级医生能达到资深医生水平。据悉，达摩院自2017年成立起布局医疗AI，在行业内率先提出用AI识别医学影像中人眼难以察觉的细微病灶，先后研发出基于平扫CT的胰腺癌筛查AI模型DAMO PANDA、胃癌筛查AI模型DAMO GRAPE、肠癌筛查AI模型DAMO COCA等，相关成果三次登上《自然 · 医学》，进入国家药品监督管理局的创新通道，并获美国食品药品监督管理局（FDA）“突破性医疗器械”认定。
