A new artificial intelligence tool is being tested in a Chinese hospital to detect pancreatic cancer from routine CT scans, potentially catching the disease earlier than traditional methods. The Affiliated Peoples Hospital of Ningbo University in Ningbo, China, is utilizing the AI-powered system, which identified a tumor in Qiu Sijun, a 57-year-old retired bricklayer, during a routine diabetes checkup before he experienced any symptoms.
Mr. Qiu received a call from Dr. Zhu Kelei, head of the hospital's pancreatic department, shortly after his CT scan. "I knew it couldn't be anything good," Mr. Qiu recalled. Dr. Zhu subsequently removed the tumor, highlighting the potential for early intervention made possible by the AI.
Pancreatic cancer is notoriously difficult to detect in its early stages, often presenting with vague symptoms or none at all until it has progressed. This late detection contributes to its high mortality rate. The AI tool aims to address this challenge by analyzing CT scans for subtle indicators that might be missed by the human eye.
The AI system is integrated into self-service kiosks at the hospital, allowing for widespread screening. While the specific algorithm and its development process were not detailed, the hospital emphasized its potential to improve early diagnosis rates.
Dr. Zhu Kelei believes this technology could revolutionize pancreatic cancer screening. "Early detection is crucial for successful treatment," he stated. "This AI tool gives us a significant advantage in identifying tumors at a stage when they are still resectable."
The use of AI in medical imaging is rapidly expanding, with applications ranging from detecting lung nodules to identifying signs of Alzheimer's disease. Experts caution that AI tools should be used as an adjunct to, not a replacement for, human expertise. Further studies are needed to validate the effectiveness and accuracy of the pancreatic cancer detection AI in larger populations and diverse settings. The hospital plans to continue testing and refining the tool, with the goal of making it a standard part of their diagnostic protocol.
