Detection of urolithiasis: comparison of 100% tube exposure images reconstructed with filtered back projection and 50% tube exposure images reconstructed with sinogram-affirmed iterative reconstruction.

Purpose: To compare images acquired with 50% tube exposure with a dual-source computed tomographic (CT) scanner and reconstructed with sinogram-affirmed iterative reconstruction (SAFIRE) with 100% exposure images reconstructed with filtered back projection (FBP) for reader ability to detect stones, reader confidence, and findings outside the urinary tract.

Materials And Methods: In this HIPAA-compliant, institutional review board-approved study, imaging examinations in 99 patients with urolithiasis were assessed. Data from both tubes were reconstructed with FBP; data from the primary tube only were reconstructed with SAFIRE.

Imaging evaluation of laparoscopic greater curvature plication: preliminary observations.

Objective: The purpose of this article is to assess normal imaging findings and complications after laparoscopic greater curvature plication on luminal upper gastrointestinal studies and CT.

Materials And Methods: This was a retrospective chart review of 24 adults who underwent laparoscopic greater curvature plication between 2008 and 2011. Seventeen patients (70.
