A multi-institutional assessment of low-dose protocols in chest computed tomography: Dose and image quality.

Background: Low-dose CT (LDCT) chest protocols have widespread clinical applications for many indications; as a result, there is a need for protocol assessment prior to standardization. Dalhousie University and Oslo Metropolitan University have a formally established cooperative relationship.

Purpose: The purpose is to assess radiation dose and image quality for LDCT chest protocols in seven different hospital locations in Norway and Canada.

Strategies for calculating contrast media dose for chest CT.

Background: Total body weight (TBW) is a frequently used contrast media (CM) strategy for dose calculation in enhanced CT, yet it is suboptimal as it lacks consideration of patient characteristics, such as body fat percentage (BFP) and muscle mass. Alternative CM dosage strategies are suggested by the literature. Our objectives were to analyze the CM dose impact when adjusting to body composition using methods of obtaining lean body mass (LBM) and body surface area (BSA) along with its correlation with demographic factors in contrast enhanced chest CT examinations.

A survey of local diagnostic reference levels for the head, thorax, abdomen and pelvis computed tomography in Norway and Canada.

Background: Computed tomography (CT) contributes to 60% of the collective dose in medical imaging. Literature has demonstrated that patient dose varies across regions and countries. Establishing diagnostic reference levels (DRLs) contributes to the optimization of clinical practices and radiation protection.

Translating interprofessional collaboration competencies to an international research team.

Introduction: While there has been strong emphasis on enhancing interprofessional education and interprofessional care in the published literature, there is relatively little literature focused on advancing interprofessional research. In extrapolating from the current frameworks of interprofessional collaboration (IPC), it becomes clear that the core competencies of IPC are transferable to research teams. The aim of this paper is to present our experience of an international research team framed within core competencies for IPC.

International Student Mobility in Radiography: Agency and Experience.

Purpose: The purpose of the study was to evaluate student exchange experiences to gain insight into what students perceived as benefits, challenges, and overall areas for improvement that might inform and enhance future exchange projects.

Methods: A general program evaluation survey, adapted to address the project objectives, was conducted. Eight students from Norway, Canada, and South Africa participating in an international exchange project completed an online survey.

Are Antimony-Bismuth Aprons as Efficient as Lead Rubber Aprons in Providing Shielding against Scattered Radiation?

Aim: The aim of this study is to compare the absorption ability of two lead-free aprons with a lead apron.

Method: The absorption ability of three aprons was measured and compared; Opaque Fusion 0.35 mm (OpaqFu) bilayer apron containing bismuth and antimony, No Lead 0.
