Core Tip
Core Tip: This first national survey reveals that while Chinese digestive disease clinicians are largely unfamiliar with Phased-array computed tomography, they strongly endorse its potential to address critical gaps in digestive disease care, especially early cancer detection and precise intervention. The study identifies specific high-priority applications, quantifies significant differences in perception based on physician specialty and practice setting, and outlines key barriers – training, evidence, cost – that must be overcome for successful clinical translation. The findings provide a strategic, evidence-based roadmap for developers and clinical researchers to guide the future of this disruptive imaging technology.
