Polyp conspicuity. 3D images from a 66 year old male with BMI of 36 with a 7 mm sessile polyp in the ascending colon. This was one of the largest patients in our series, and even a small polyp remains conspicuous on SD-FBP (A), RD-FBP (B), RD-PICCS (C), RD-MBIR (D), RD-ASIR (E). The effective dose of the low dose series was 2.6 mSv, compared to 8.8 mSv for the standard dose.
