霍去病

快科技8月24日消息，据阿里巴巴公众号消息，近期，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。在两个月的真实世界前瞻临床试验中，DAMO LiON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）。    Actor Rajashekar who recently returned to cinemas with Nithiin-starrer Extraordinary suffered leg injury while shooting for his upcoming film. The incident happened during shooting an action-related sequence in Medchal (Hyderabad) on November 25. The mishap resulted in multiple fractures to Rajashekar’s ankle.          Rajasekhar undergoes three-hours surgery     According to sources from the unit, Rajashekar suffered a right ankle bimalleolar dislocation with a compound fracture. This is considered a severe injury associated with high-impact trauma. After the incident happened, the actor was immediately taken for medical evaluation. Doctors recommended an urgent surgical intervention to prevent further complications. Rajasekhar subsequently underwent a major surgery lasting nearly three hours.A statement from Rajasekhar’s team read, “The surgical procedure involved right ankle open reduction and internal fixation (ORIF) with K-wires for the lateral malleolus. Open reduction and internal fixation using cannulated cancellous screws and a semi-tubular plate for the medial malleolus. Trans-fixation of the tibia using a wire passed through the calcaneum and talus.” Despite the complexity of the procedure and the intense pain Rajashekar endured it all. The surgery was successful, and the actor is currently recuperating.                    Doctors advised four weeks rest     Doctors have advised Rajashekar four weeks of rest emphasizing that the operated leg must remain immobile during the crucial healing phase. The actor will be back in action in the last week of January and resumes shooting for the film depending on his recovery progress. Apart from shooting for his upcoming film Biker, Rajashekar is also working on two yet-to-be-titled films. Fans and industry colleagues have been sending wishes for his speedy recovery. The actor had earlier suffered a similar left-leg injury while shooting for the 1989 action thriller, Magadu.In a career spanning more than four decades, Rajashekar is known for performing daredevil stunts and high-octane action sequences. He was known as the “Angry Young Man” of Tollywood for his intense and rebellious roles.Also Read: Ram Charan’s Peddi Vs Nani’s The Paradise! Can a Box Office Clash Be Avoided?

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。研究团队随后将AI模型实际部署到医院，参与日常阅片，当AI与医生初诊结论不一致时，病例会交给资深放射科医生复核，必要时升级至多学科团队（MDT）讨论。

B | 两个月内，AI共阅读1万多名患者的增强CT影像，辅助医生抓出15例原本被忽略的肝转移，推动改变了这些患者的治疗方案。

C | 据官方介绍，早在2017年，达摩院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。目前已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。
