In the absence of a formal dedicated paediatric medical imaging subspecialty, this study undertook to understand student radiographers' experiences and perspectives on paediatric medical imaging.

Methods: The study entailed a descriptive cross-sectional survey design entailed a 51-item closed and open-ended response questionnaire using a total sampling method.

Australian graduate radiographers' perspectives and experiences of work readiness.

Introduction: Graduate radiographers entering their qualified positions need to orientate and familiarise themselves with a rapidly changing work environment to deliver a high standard of diagnostic imaging services. During this transitional phase, these newcomers also strive to meet self-expectations and workplace expectations. This study was performed to understand the work readiness perspectives and initial experiences of graduate radiographers on beginning their newly qualified roles.

Diagnostic radiography students' perspectives on cultural competence and safety.

Introduction: Cultural competency and safety are essential components to consider in the provision of person-centred equitable healthcare. Therefore, student radiographers' learning should include the necessary knowledge, skill sets and competence to recognise the patient's unique characteristics to enable culturally competent and safe medical imaging services. Therefore, this study explored undergraduate and postgraduate diagnostic radiography students' perspectives on cultural competency and safety.

Computer assisted diagnosis of Alzheimer's disease using statistical likelihood-ratio test.

The purpose of this work is to present a computer assisted diagnostic tool for radiologists in their diagnosis of Alzheimer's disease. A statistical likelihood-ratio procedure from signal detection theory was implemented in the detection of Alzheimer's disease. The probability density functions of the likelihood ratio were constructed by using medial temporal lobe (MTL) volumes of patients with Alzheimer's disease (AD) and normal controls (NC).

Introduction: Interprofessional education (IPE) in medical radiation education is designed to enhance both student and longer-term patient outcomes. This scoping review aims to provide an overview of the available evidence and examine the effectiveness of IPE strategies used to enhance the development of medical radiation science (MRS) students.

Methods: Medline, CINAHL, Cochrane Library and Emcare were searched for articles which employed an experimental study design to quantitatively assess the effectiveness of IPE for MRS students.

Radiation Protection among South African Diagnostic Radiographers-A Mixed Method Study.

Worldwide, radiographers' radiation protection practices vary. In South Africa, evidence of diagnostic radiographers' suboptimal radiation protection practices has been reported, but the reasons for these practices and suggestions to improve practices were lacking. Therefore, this study explored radiation protection among South African diagnostic radiographers.

Collimation and cropping in diagnostic radiography: How concerned are we?

This editorial examines current collimation and cropping practices in general radiography. We critically reflect on whether we are concerned by the practice of collimation creep amongst radiographers. Discussions around policy, evidence‐based practice and potential hypocrisies are outlined in this editorial piece.

An exploratory study on recently qualified Australian radiographers' expectations and experiences in emergency and trauma imaging.

Background: Radiographers provide imaging services in multiple healthcare settings, including emergency and trauma. Transitioning to a qualified radiographer is already a time of vulnerability - with the increasing complexity and unpredictable nature of the emergency and trauma healthcare environment, recently qualified radiographers may experience this environment distinct from other service delivery areas.

Objective: The study explored recently qualified radiographers' expectations and experiences in emergency and trauma imaging service delivery.

The influence of patient positioning on radiation dose in CT imaging: A narrative review.

Background And Purpose: Although it is fundamental for optimal scanner operation, it is generally accepted that accurate patient centring cannot always be achieved. This review aimed to examine the reported knowledge of the negative impact of patient positioning on radiation dose and image quality during CT imaging. Furthermore, the study evaluated the current optimisation tools and techniques used to improve patient positioning relative to the gantry iso-center.

Radiographers' experiences and perspectives of forensic imaging in Australia: A qualitative study.

Introduction: Forensic imaging plays a pivotal role regarding medico-legal issues by investigating the cause(s) of injuries to living or deceased individuals. There is currently a gap in the literature on forensic imaging due to limited national and international guidelines, protocols and scope of duties and responsibilities of radiographers undertaking forensic imaging. Thus, this study aimed to investigate the gap by exploring the experiences and perspectives of radiographers on forensic imaging in Australia.
