To compare lesion detection and image quality of chest computed tomographic (CT) images acquired at various tube current-time products (40-150 mAs) and reconstructed with adaptive statistical iterative reconstruction (ASIR) or filtered back projection (FBP). ⋯ http://radiology.rsna.org/lookup/suppl/doi:10.1148/radiol.11101450/-/DC1.

To estimate the relative yield of therapeutic flexible sigmoidoscopy compared with complete optical colonoscopy for isolated left-sided polyps (≥6 mm in diameter) identified at screening computed tomographic (CT) colonography. ⋯ For patients with left-sided-only polyps detected at CT colonography, the additional yield of complete optical colonoscopy beyond the expected reach of flexible sigmoidoscopy is very low and may not justify the added costs, potential risks, and procedural time.

Honorary authorship in radiologic research articles: assessment of frequency and associated factors.
To quantify the frequency of perceived honorary authorship in radiologic journals and to identify specific factors that increase its prevalence. ⋯ http://radiology.rsna.org/lookup/suppl/doi:10.1148/radiol.11101500/-/DC1.
