Spatial Resolution Fidelity Comparison Between Energy Integrating and Deep Silicon Photon Counting CT: Implications for Pulmonary Imaging.

Purpose: We investigated spatial resolution loss away from isocenter for a prototype deep silicon photon-counting detector (PCD) CT scanner and compare with a clinical energy-integrating detector (EID) CT scanner.

Materials And Methods: We performed three scans on a wire phantom at four positions (isocenter, 6.7, 11.

Sonographic evaluation of the association between calcific tendinopathy and rotator cuff tear: a case-controlled comparison.

Objectives: To compare the incidence of rotator cuff (RC) tears on shoulder ultrasounds of patients with RC calcific tendinopathy (CaT) to that of a control group without CaT.

Method: In this retrospective case-control study, 50 shoulder ultrasounds of patients with CaT were compared independently by 2 musculoskeletal radiologists to 50 patients from a control group without CaT to catalog the number and type of RC tears. RC tears in the CaT group were further characterized based on location, into tears in the specific tendon(s) containing calcium versus all tendon tears.

Trend Toward High-Volume Hospitals and the Influence on Complications in Knee and Hip Arthroplasty.

Background: Hospitals in which a high volume of arthroplasty procedures are performed have been observed to have better outcomes. As the number of arthroplasties has increased, it is not known whether surgical cases have shifted to high-volume hospitals. In this study, we examined the change in the volume of arthroplasties to provide a contemporary definition of "high-volume" centers, quantified surgical volume that shifted to high-volume centers, and investigated the resulting effect on complications.

Scoring the SF-36 in Orthopaedics: A Brief Guide.

The Short Form-36 (SF-36) is the most widely used health-related quality-of-life measure in research to date. There are currently two sources for the SF-36 and scoring instructions: licensing them from Optum, Inc., or obtaining them from publicly available documentation from the RAND Corporation.
