END-TO-END AUDIT: COMPARISON OF TLD AND LITHIUM FORMATE EPR DOSIMETRY

, 2019
The aim of this study was to test two different solid state dosimetry systems for the purpose of end-to-end audits of radiotherapy volumetric modulated arc therapy (VMAT) technique; a lithium formate electron paramagnetic resonance system and a lithium ...

Current Evidence on Best Practice Dental Survivorship Care for People With Head and Neck Cancer: An Overview of Systematic Reviews and Emerging Evidence

Head &Neck, EarlyView.
ABSTRACT Introduction Head and neck cancer (HNC) survival is improving, increasing the need to address long‐term survivorship issues. Dental survivorship—care before, during, and after treatment—remains inconsistent across services. We conducted a review of systematic reviews and emerging evidence to inform contemporary dental survivorship care for HNC

The Importance of Dosimetry Standardization in Radiobiology

, 2013
Radiation dose is central to much of radiobiological research. Precision and accuracy of dose measurements and reporting of the measurement details should be sufficient to allow the work to be interpreted and repeated and to allow valid comparisons to be

Epigenetic Dysregulation of Somatostatin Receptors (SSTR) 1–5 and Therapeutic Implications in Neuroendocrine and Non‐Neuroendocrine Malignancies

International Journal of Cancer, EarlyView.
ABSTRACT Somatostatin receptors (SSTR) mediate the antiproliferative, antisecretory, and proapoptotic effects of somatostatin and its synthetic analogs. Their surface expression on neuroendocrine tumor (NET) cells is required for somatostatin analog therapy and radiopharmaceutical therapy (RPT).

Neutron/Gamma Mixed Spectrum Radiolysis-based Aqueous Dosimetry [PDF]

, 2007
This work develops a method to use an aqueous dosimeter in a mixed radiation field to determine separate measurements of neutron and gamma dose. Based on radiolysis of both Fricke and Methyl Viologen (MV) solutions, activation analysis and reactor ...

Dose‐Dependent Efficacy of Radioiodine Therapy in Pediatric Graves’ Disease: A Retrospective Study of Hypothyroidism Risk and the Predictive Role of Thyroid Hormone Parameters

iRADIOLOGY, EarlyView.
RAI therapy demonstrated time‐dependent efficacy in pediatric Graves' disease, with gradually increasing treatment success and hypothyroidism incidence during follow‐up. Higher planned activity (≥ 0.15 mCi/g) was associated with a higher successful rate than lower planned activity (< 0.15 mCi/g), and LASSO analysis identified FT3 and TSH as candidate ...

Determination of metals concentration in sedimentary profiles from lagoons affected by the tailings from the collapse of the Fundão dam

Brazilian Journal of Radiation Sciences
The collapse of the Fundão dam in Mariana released more than 59 million m³ of tailings, which flowed almost 700 kilometers along the Doce river, through the states of Minas Gerais and Espírito Santo, reaching the estuary and into the Atlantic Ocean.

The Impact of Genetic Polymorphisms on Genotoxicity (DNA Damage) Among Children Exposed to Environmental Mutagens: A Systematic Review

Journal of Applied Toxicology, EarlyView.
ABSTRACT Children, as a particularly vulnerable group, are more susceptible to these mutagens due to their developing immune systems, higher physiological vulnerability, and increased exposure through behaviors like outdoor play and hand‐to‐mouth activities. This review aims to investigate the relationship between these environmental exposures, genetic

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 ...
