One-mSv CT colonography: Effect of different iterative reconstruction algorithms on radiologists’ performance

•Mean effective radiation dose for 120kVp/100kVp with 10mAs CT colonography was 1mSv.•Image noise significantly decreased from FBP to ASIR and MBIR algorithms.•Per-polyp sensitivity of 1mSv CT colonography reconstructed with FBP was not acceptable.•Per-polyp sensitivity of 1mSv CT colonography can b...
