Intrafraction motion and impact of margin reduction for MR‐Linac online adaptive radiotherapy for pancreatic cancer treatments

Journal of Medical Radiation Sciences, Volume 72, Issue 1, Page 17-24, March 2025.
This analysis included quantification of intrafraction motion in pancreas stereotactic ablative radiotherapy treated on the MR‐Linac, leading to the development of adjusted (PTV) margins. Intrafraction motion indicated an average target displacement of 1–3 mm, resulting in an adjusted PTV margin of 2 mm in the right–left and superior–inferior ...

The Prognostic Value of EDRIC and Its Association With Radiation‐Induced Lymphopenia in Patients With Esophageal Cancer Undergoing Radical Radiotherapy: A Single‐Center Chinese Study

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT This study aimed to evaluate the predictive value of the estimated dose of radiation to immune cells (EDRIC) in patients with esophageal cancer receiving radical radiotherapy. We retrospectively reviewed the data of patients with esophageal cancer who underwent definitive radiotherapy at our institution.

Radiation‐Induced Cutaneous Tissue Reactions in Neurointerventional Procedures: A Systematic Review of Reported Effects and Associated Dose Levels

Journal of Medical Imaging and Radiation Oncology, EarlyView.
ABSTRACT Neurointerventional procedures can deliver high localised skin doses and may cause radiation‐induced cutaneous tissue reactions, yet the doses at which these occur have not been synthesised specifically for this setting. We systematically reviewed reported cutaneous reactions and associated radiation doses after fluoroscopy‐ or digital ...

OSL at elevated temperature of smart chip cards for retrospective dosimetry

Radiation Physics and Chemistry, 2023
Smart chip cards are a promising material in retrospective dosimetry due to their high collectability with low replacement cost. In this study, dose reconstruction using OSL at elevated temperatures for various chip cards was investigated. The approximate spectral emission of the chip cards was determined through a comparison of radiation-induced and ...

Lung V5 and Planning Target Volume/Lung Volume Ratio as Independent Risk Factors for ≥Grade 2 Radiation Pneumonitis after Moderately Hypofractionated Radiotherapy: A Retrospective Study

Asia-Pacific Journal of Clinical Oncology, EarlyView.
Lung V5 and the planning target volume/lung volume ratio were identified as independent dosimetric risk factors for clinically significant radiation pneumonitis following moderately hypofractionated radiotherapy for lung cancer. Maintaining V5 < 35% may help mitigate this risk in clinical practice.

Retrospective Analysis of Survival and Adverse Effects Associated With Stereotactic Body Radiation Therapy in 12 Dogs With Hepatocellular Carcinoma

Veterinary and Comparative Oncology, EarlyView.
ABSTRACT This retrospective analysis evaluated 12 dogs with hepatocellular carcinoma (HCC) who received stereotactic body radiation therapy (SBRT). Dogs received between 6 and 25 Grey (Gy) per fraction for 1–5 fractions for a total dose of 13–30 Gy. Eleven patients (92%) experienced acute adverse effects (AE), with the majority being VRTOG grade 2–3 ...

Evaluating Human Perception Thresholds in Magnetic Stimulation Using Experimental Measurements and Modelling

Bioelectromagnetics, Volume 47, Issue 6, September 2026.
ABSTRACT This preregistered study investigated whether induced electric fields alone could predict human perception thresholds in magnetic stimulation. Using a figure‐of‐eight magnetic coil placed on the forearm, perception thresholds were collected from 24 healthy participants using the method of adjustment in 12 stimulation conditions. Subject‐fitted,
