DaYi Smart Imaging: AI-Assisted Medical Image Reading by Alibaba DAMO Academy 89

What is Da Yi Zhi Ying?

Da Yi Zhi Ying is an intelligent imaging-reading product independently developed by Alibaba DAMO Academy's medical ai lab. By combining routine chest and abdominal CT plain scans with AI technology, it helps doctors perform disease screening, diagnosis, treatment, and follow-up.

Leveraging the powerful computing capabilities of Alibaba Cloud, Alibaba DAMO Academy's medical AI imaging technology empowers AI-based cancer diagnosis and screening in medical imaging. The technology is dedicated to early cancer screening, tumor screening, and the early detection and precise treatment of various acute and chronic diseases. Through "plain CT + AI," it enables multi-cancer screening, significantly improving diagnostic efficiency, reducing the risk of missed diagnoses, and advancing smart healthcare to a higher level.

Features of Da Yi Zhi Ying

• Multi-disease screening: Through routine chest and abdominal CT plain scans combined with AI technology, "Da Yi Zhi Ying" can simultaneously screen for 8 types of cancer, including pancreatic cancer, liver cancer, esophageal cancer, gastric cancer, and colon cancer, as well as 5 types of chronic diseases, including osteoporosis, fatty liver, and pulmonary nodules.

• Efficient screening: AI technology has greatly improved screening efficiency, from the traditional 5-15 minutes required for a human to assess a single disease, to 2-3 minutes to assess multiple diseases.

• High accuracy: Its pancreatic cancer detection model PANDA achieves a specificity of 99.9% and a sensitivity of 92.9%, identifying 31 clinically missed lesions during large-scale validation.

• Full-process assistance: It is not only used for disease screening, but also assists doctors throughout the entire process of diagnosis, treatment, and follow-up.

Technical Principles of Da Yi Zhi Ying

• Plain CT + AI: It utilizes routine chest and abdominal CT plain scan images, combined with AI algorithms for analysis. AI technology can rapidly process large volumes of imaging data and identify potential lesion areas.

• Multi-disease screening: A single examination can screen for multiple cancers and chronic diseases. Currently, it is capable of screening for 8 types of cancer, including pancreatic cancer, liver cancer, esophageal cancer, gastric cancer, and colon cancer, as well as 5 types of chronic diseases, including osteoporosis, fatty liver, and pulmonary nodules.

Application Scenarios of Da Yi Zhi Ying

• Primary healthcare: It has been piloted in primary hospitals in Lishui, Quzhou, and other areas of Zhejiang, assisting in enhancing the early cancer screening capabilities of primary medical institutions.

• Large-scale screening: It is suitable for routine physical examinations and large-scale cancer screening programs in hospitals, and can improve the early cancer detection rate among asymptomatic populations.

• International cooperation: It collaborates with international organizations such as the World Health Organization to promote the international application of early cancer screening technologies.

Application Results of Da Yi Zhi Ying

• Improved diagnostic efficiency: Traditional manual image reading requires 5-15 minutes to assess a single disease, while "Da Yi Zhi Ying" can assess multiple diseases within 2-3 minutes.

• Enhanced diagnostic accuracy: AI technology can reduce misdiagnoses and missed diagnoses caused by human factors. Relevant studies show that its accuracy in identifying the presence of lesions reaches 92.9%, and its accuracy in identifying the absence of disease reaches 99.9%.

How to Use Da Yi Zhi Ying

• For patients: Patients only need to undergo routine chest and abdominal CT plain scan examinations, with no additional contrast agents or special examinations required.

• For doctors: Doctors input the patient's CT imaging data into the "Da Yi Zhi Ying" system, which automatically analyzes and marks potential lesion areas, assisting doctors in diagnosis and decision-making.

In February 2024, Alibaba's "Medical AI Multi-Cancer Early Screening Public Welfare Project" was launched in Lishui, Zhejiang, relying on "Da Yi Zhi Ying" technology. The project was first deployed at Lishui Central Hospital and Jingning County People's Hospital, with Alibaba Foundation supporting the initiative in a purely public welfare format.In addition to Lishui, this technology has also been piloted in primary hospitals in Quzhou and other areas of Zhejiang. In the future, Alibaba plans to extend this model to hospitals in other cities across the country.
