AI Advances in Early Pancreatic Cancer Detection Using CT Scans

What is it about?

The study systematically evaluated AI-based techniques from 2018 to 2025 for analyzing pancreatic tumors using CT images, identifying 33 eligible studies from an initial pool of 236 records across databases like PubMed and Scopus. The review categorized these studies into four themes: AI-driven segmentation for tumor localization, deep learning-based tumor classification, CT-based radiomics and feature-driven analysis, and early detection models. The research emphasized the effectiveness of AI in enhancing diagnostic accuracy through segmentation, classification, and hybrid techniques, while also focusing on datasets, evaluation metrics, and clinical applicability. The findings highlighted significant advancements in machine learning and deep learning architectures, such as CNNs and attention-based methodologies, which improved pancreas segmentation and tumor detection. Despite progress, challenges such as anatomical variability, class imbalance, and model interpretability in multi-institutional studies persist, complicating large-scale clinical translation. Furthermore, the study identified ongoing challenges with integrating AI into clinical workflows, domain adaptation, and ensuring consistent model performance across different imaging platforms.
