Longitudinal 1H and 129Xe Lung MRI in Patients With Post‐COVID Residual Lung Abnormalities

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background It is unclear how lung function may recover in patients with residual lung abnormalities (RLAs) following COVID‐19 pneumonia. Purpose To evaluate lung function trends over time in patients with RLAs following hospitalization due to COVID‐19. Study Type Prospective, multicenter longitudinal cohort study.

Approaches to Computed Tomography Education for Radiography Students

Journal of Medical Radiation Sciences, EarlyView.
The aim of this narrative review was to explore the current published literature relating to CT teaching methods and assessment of diagnostic radiography students during university training. Existing CT education evaluations focus on student satisfaction and usability of tools, with post‐lesson knowledge gains reported. Future work should shift towards

Chest X‐Ray Imaging Algorithms for Optimising the Visualisation of Medical Lines and Tubes: A Study With Student Radiographers

Journal of Medical Radiation Sciences, EarlyView.
Imaging post‐processing algorithms are helpful in improving the visibility of chest lines and tubes on standard chest X‐rays. Examples include the advanced edge enhancement and grey‐scale inversion, and this study evaluates the usefulness of these algorithms for enhancing visual image quality and reader confidence among student radiographers.

Radiation Dose Optimisation Through Artificial Intelligence (AI)‐based Auto‐Thorax Collimation

Journal of Medical Radiation Sciences, EarlyView.
This study evaluated AI‐based Auto‐Thorax Collimation (ATC) for radiation dose optimisation in posteroanterior chest radiography compared with manual collimation. ATC demonstrated tighter lateral collimation and reduced inter‐operator variability while maintaining comparable repeat rates.

Adherence to Diagnostic Imaging Pathways for Patients Presenting to Emergency Departments With Undifferentiated Acute Abdominal Pain: Impact on Radiation Exposure and Multiple Imaging Testing

Journal of Medical Radiation Sciences, EarlyView.
There are many recommendations and guidelines when it comes to medical imaging, but just how effective and useful are they? This article examines this topic with regards to the RANZCR Imaging Pathways and acute abdominal pain. ABSTRACT Introduction The Diagnostic Imaging Pathways (DIP) are a tool that has been developed to assist physicians with ...

Prone Breast Radiotherapy on the MR‐Linac: A Technical Note on Skin‐Couch Contact Dose Effects

Journal of Medical Radiation Sciences, EarlyView.
This retrospective planning study evaluated the dosimetric effects of skin‐couch contact during prone APBI on a 1.5 T MR‐Linac by comparing treatment plans calculated with and without a magnetic field. While the presence of the magnetic field increased overall superficial skin dose, it consistently reduced dose at the skin‐couch contact region ...

Paediatric computed tomography diagnostic reference levels in Africa: A systematic review

Journal of Medical Radiation Sciences, Volume 72, Issue 1, Page 139-147, March 2025.
Improvements in computed tomography (CT) technology have increased its applications in medical imaging. Variations in the paediatric DRLs indicate that harmonisation and standardisation of paediatric CT protocols are essential for the optimisation of paediatric doses. Abstract Introduction Improvements in computed tomography (CT) technology in terms of

Size‐specific dose estimates calculated using patient size measurements from scanned projection radiograph in high‐resolution chest computed tomography

Journal of Medical Radiation Sciences, Volume 72, Issue 1, Page 85-92, March 2025.
This study established that patient's lateral width measurements made from scanned projection radiograph (SPR) is an overestimate compared to those measured from tomographic slices by about 10%. Size‐specific dose estimates (SSDE) calculated using lateral width measured from SPR correlates well with SSDE calculated using water equivalent diameter of ...

Optimising hypoxia PET imaging and its applications in guiding targeted radiation therapy for non‐small cell lung cancer: a scoping review

Journal of Medical Radiation Sciences, Volume 72, Issue 1, Page 106-118, March 2025.
This review article reports that quantification of hypoxic volumes using PET in the pre‐radiation therapy setting is of prognostic value and indicative of treatment response in non‐small cell lung cancer. Abstract Introduction Non‐small cell lung cancer (NSCLC) is the leading cause of cancer‐related death. Definitive treatment includes chemotherapy and
