Maximising polyp detection at CT colonography (CTC) requires a combination of optimised technique, meticulous interpretation, and disciplined reporting strategy. This talk will explore evidence-based strategies to enhance detection rates, including bowel preparation and distension, scanning protocols, and the effective use of both 2D and 3D interpretation workflows. I will highlight common perceptual pitfalls, subtle lesion characteristics, and practical approaches to reducing errors. Real case examples will illustrate how structured search patterns and high-quality image review can enhance diagnostic performance and ultimately improve patient outcomes.
