High‐Content Screening Comparison of 1R6F Cigarette Smoke Extract and Selected Heated Tobacco and Electronic Vapour Product Aerosol Extracts in Endothelial and Bronchial Epithelial Cell Models

Journal of Applied Toxicology, EarlyView.
ABSTRACT Cigarettes induce oxidative stress and DNA damage, processes that contribute to cardiovascular and pulmonary disease. High content screening (HCS) is an increasingly valuable tool for comparative toxicology because it enables simultaneous quantification of multiple mechanistic endpoints at single‐cell resolution. In this study, HCS was used to

Mapping the Landscape of Over‐Scanning in CT Imaging: A Scoping Review

Journal of Medical Radiation Sciences, EarlyView.
Over‐scanning in CT is highly prevalent and contributes to unnecessary radiation exposure, with notable impact on radiosensitive organs. Standardised protocols and AI‐assisted planning show strong potential to optimise scan range and reduce excess dose.

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 ...

Dosimetric Outcomes of Definitive Radiation Therapy to Anal Squamous Cell Carcinoma in a Single Institution Using Volumetric Modulated Arc Therapy Evaluated Against Australian and International Treatment Planning Guidelines

Journal of Medical Radiation Sciences, EarlyView.
This study evaluated 43 clinically approved VMAT plans for anal squamous cell carcinoma (SCC) against RTOG, eviQ, ANROTAT and departmental planning guidelines to assess the achievability of current dose constraints. While most target coverage and median OAR dose objectives were within protocol, not all constraints were consistently met, supporting the ...

Esr dosimetry of fossil enamel: Some comments about measurement precision, long-term signal fading and dose-response curve fitting

, 2013
This work deals with the specific studies of three main sources of uncertainty in electron spin resonance (ESR) dosimetry/dating of fossil tooth enamel: (1) the precision of the ESR measurements, (2) the long-term signal fading the selection of the ...

Dosimetry, Toxicity and Stability Associated With a Hyaluronic Acid‐Based Prostate‐Rectal Spacing Device During Prostate Radiation Therapy: A Retrospective Comparative Analysis

Journal of Medical Radiation Sciences, EarlyView.
Rectal spacers composed of stabilised hyaluronic acid facilitated a favourable toxicity profile compared to no spacing during prostate radiation therapy. Acute GI toxicity (grade ≥ 1) was lower in the spacer cohort (23.5% vs. 48.0%; odds ratio = 0.33, p = 0.05) with grade ≥ 2 toxicity substantially lower (2.9% vs. 20.0%).

Application of the Linear-Quadratic model to targeted radionuclide therapy [PDF]

, 2011
PhDThe principal aim of this work was to test the hypothesis that the Linear-Quadratic (LQ) model of cell survival, developed for external beam radiotherapy (EBRT), could be extended to targeted radionuclide therapy (TRT) in order to predict dose ...
