Deep learning CT model for stratified diagnosis of pancreatic cystic neoplasms: multicenter development, validation, and real-world clinical impact
Pancreatic cystic neoplasms (PCN) are critical precursors for early pancreatic cancer detection, yet current diagnostic methods lack accuracy and consistency. This multicenter study developed and validated an artificial intelligence (AI)-powered CT model (PCN-AI) for improved assessment. Using contrast-enhanced CT images from 1835 patients, PCN-Al extracted 63 quantitative features to classify PCN subtypes through four hierarchical tasks. A multi-reader, multi-case (MRMC) study demonstrated that AI assistance significantly improved radiologists' diagnostic accuracy (AUC: 0.786 to 0.845; p < 0.05) and reduced interpretation time by 23.7% (5.28 vs. 4.03 minutes/case). Radiologists accepted AI recommendations in 87.14% of cases. In a prospective real-world cohort, PCN-Al outperformed radiologist double-reading, providing actionable diagnostic benefits to 45.45% of patients (5/11) by correctly identifying missed malignant PCN cases, enabling timely intervention, and simultaneously reducing clinical workload by 39.3%. PCN-Al achieved robust performance across tasks (AUCs: 0.845–0.988), demonstrating its potential to enhance early detection, precision management, and diagnostic efficiency in clinical practice.
Key Takeaway: PCN-AI transforms pancreatic cancer detection with AI-driven precision, offering early intervention and significant workload reduction.

Real-World Malignant IPMN Case Identified by PCN-AI
In a real-world prospective study, PCN-AI assisted in correctly identifying a malignant IPMN case initially misdiagnosed as precancerous by traditional double-reading. A 52-year-old female patient's initial diagnosis was revised from precancerous IPMN to malignant IPMN with a 0.679 probability after PCN-AI's exhaustive analysis of critical indicators. This led to multidisciplinary consultation and subsequent surgery, highlighting AI's capacity for reinforcing guideline adherence and personalizing risk stratification.
Key Findings:
- Initial misdiagnosis of precancerous IPMN by human readers.
- PCN-AI's analysis led to revised diagnosis of malignant IPMN.
- 0.679 probability of malignancy assigned by AI.
- Confirmed by multidisciplinary team and surgery.
- Demonstrates AI's role in preventing missed malignant cases.
