AI发现医生看不见的隐藏心脏病风险,近90%准确率远超人类专家|Nature子刊
量子位· 2025-07-07 06:13
闻乐 发自 凹非寺 量子位 | 公众号 QbitAI AI现在真能救命! 传统的心脏MRI(磁共振成像)检查可能遗漏的关键风险信号,现在能够被AI捕捉了。 登上《Nature》子刊的最新研究—— 多模态 AI模型 MAARS ,首次用深度学习方法处理原始MRI图像,实现了对心源性猝死风险 (SCDA)的高精度预测,准确率高达 89% 。 这项研究来自约翰霍普金斯大学。 目前, 肥厚型心肌病 的临床诊断准确率仅50%,这使得医生在决定患者是否需要植入除颤器等保护措施时,常常面临"掷骰子"般的选择。 MAARS模型采用3D视觉 Transformer 架构,直接分析LGE-CMR(增强心血管磁共振成像)原始信号强度,避免了人工解读的主观性。 该模型能够从原始MRI图像中挖掘 隐藏的 纤维化瘢痕模式。 这些以往被医生忽略的细微结构变化,正是触发致命性心律失常的关键信号。 现在,MAARS可以将这些隐藏的病理信息转化为可量化的风险指标,提前发现连资深心脏专家都有可能忽略的致命风险。 在40岁到60岁人群中诊断准确率高达93% MAARS的核心优势在于通过多模态数据融合与 3D-ViT 技术,首次实现对心脏纤维化瘢痕的 ...

提升中国病理诊断水平,瑞金医院联合华为开源病理大模型
Guan Cha Zhe Wang· 2025-07-06 05:15
Core Viewpoint - The RuiPath pathology model, developed by Ruijin Hospital in collaboration with Huawei, aims to enhance the efficiency and accuracy of pathology diagnostics in China by leveraging AI technology [1][5]. Group 1: Model Development and Features - The RuiPath model is a clinical-grade multimodal pathology model that covers 90% of the annual cancer incidence in China, addressing 19 common cancer types and hundreds of auxiliary diagnostic tasks [1][5]. - The model has achieved state-of-the-art (SOTA) performance in 7 out of 14 auxiliary diagnostic tasks tested against 12 mainstream public datasets, surpassing the performance of Harvard's UNI2 model [4]. - The model's core "visual foundation model" was developed using over one million high-quality digital pathology slides from Ruijin Hospital, utilizing Huawei's AI toolchain for annotation, training, and fine-tuning [2][4]. Group 2: Efficiency and Impact - The implementation of the RuiPath model allows pathologists to increase their daily workload from 200-300 slides to 400-500 or more, significantly improving diagnostic efficiency [5]. - The model aims to standardize digital pathology practices across hospitals in China, enabling easier deployment and reducing training costs for other institutions [5][10]. - The collaboration between Ruijin Hospital and Huawei has streamlined the model training process, allowing for the completion of the RuiPath model development with only a 16-card cluster, making it more accessible for hospitals [10][11]. Group 3: Industry Challenges and Solutions - There is a significant shortage of pathology doctors in China, with only about 20,000 available and a gap of 140,000 needed, highlighting the importance of AI solutions in addressing this challenge [5]. - The partnership has evolved through two phases: digitalization and smart pathology, focusing on data standardization and collaborative model development [7][8]. - The use of Huawei's ModelEngine has transformed the annotation process, allowing pathologists to review over 700 slides in a day, thus enhancing both efficiency and accuracy [10].
