Schematic of polyp size measurements. The polyp shape (curved line) is intentionally skewed to exaggerate differences in the measurements, but polyps can have shapes similar to that shown. “OC Size” is the measurement of polyp size at optical colonoscopy that best approximates the maximum polyp size. “CTC Width” is the maximum width of the base of the polyp. “CTC Height” is the maximum height measured perpendicular to the base.
