A controlled trial comparing dosimetry and radiation pneumonitis between tomotherapy and IMRT in patients with lung or esophageal cancer

Journal of Applied Clinical Medical Physics, Volume 27, Issue 3, March 2026.
Abstract Backgroud The expanding clinical use of helical tomotherapy (HT) has raised concerns regarding its potential to increase low‐dose lung exposure and the risk of radiation pneumonitis (RP) in thoracic radiotherapy. While a few retrospective studies have compared dosimetric parameters and RP rates between HT and fixed‐field intensity‐modulated ...

Commissioning and validation of the Elekta One GPUMCD algorithm for an Elekta VersaHD linear accelerator

Journal of Applied Clinical Medical Physics, Volume 27, Issue 3, March 2026.
Abstract Purpose The purpose of this work was to commission and validate GPUMCD, a GPU‐accelerated Monte Carlo dose calculation engine for c‐arm Elekta linear accelerators (linac). This algorithm was recently released for clinical implementation in the Elekta One Treatment Planning System (v6.2.3, EOP). Methods A GPUMCD beam model was generated for all

Impact of Monaco sequencing parameters on monitor units, plan quality, and optimization time for Elekta Unity liver SBRT plans

Journal of Applied Clinical Medical Physics, Volume 27, Issue 3, March 2026.
Abstract Background Magnetic resonance‐guided radiation therapy (MRgRT) using the Elekta Unity MR‐linac offers significant advantages for liver stereotactic body radiation therapy (SBRT). However, the Unity is limited by a low dose rate and the lack of volumetric‐modulated arc therapy (VMAT), resulting in prolonged treatment times.

Prospective Registry and Meta‐Analysis of Particle Therapy for Hepatocellular Carcinoma: Clinical Outcomes and Real‐World Impact

Cancer Medicine, Volume 15, Issue 3, March 2026.
ABSTRACT Background and Aims This study aimed to evaluate the clinical efficacy of particle therapy for hepatocellular carcinoma (HCC) by integrating a prospective registry and a systematic meta‐analysis. Our findings also reflect the real‐world impact of this evidence, which contributed to the national health insurance approval of particle therapy for

Simulation‐free spine palliative radiotherapy enabled by AI‐adapted diagnostic CT

Medical Physics, Volume 53, Issue 3, March 2026.
Abstract Background Radiotherapy planning traditionally requires a dedicated simulation CT (sCT), which can introduce delays in initiating treatment. This is particularly impactful in spinal palliative care, where timely treatment is often important for symptom control and prevention of neurological deterioration.

Valbenazine induced acute parkinsonism in a patient with alcohol use disorder and central pontine myelinolysis

Psychiatry and Clinical Neurosciences Reports, Volume 5, Issue 1, March 2026.
Abstract Background Valbenazine is used to treat dyskinesia and is generally associated with limited side effects; however, a few cases with the adverse effect of parkinsonism are reported in the literature. In this study, we report a case of valbenazine‐induced acute parkinsonism.

Ligand‐Driven Optimization of Iron Oxide Nanoprobes for In Vivo MRI Enhancement at Ultra‐High Field

Small, Volume 22, Issue 16, 17 March 2026.
Ligand‐tailored iron oxide nanoparticles reveal how surface chemistry controls T2 relaxivity and in vivo performance in ultra‐high‐field MRI. Systematic variation of hydrophilicity and charge across five coatings modulated r2 by up to 333 mm−1 s−1, with chemical properties, rather than shell thickness, dictating magnetic dephasing and enabling reliable

Reirradiation for Recurrent Cervical Cancer Within the Previous Radiation Field Using a Bioabsorbable Spacer: A Case Report

Journal of Obstetrics and Gynaecology Research, Volume 52, Issue 3, March 2026.
ABSTRACT Reirradiation for cervical cancer recurrence in previously irradiated fields is challenging due to dose limitations. To our knowledge, this is the first case report describing successful reirradiation using a bioabsorbable spacer for vaginal cuff recurrence after initial concurrent chemoradiotherapy (CCRT) and hysterectomy. A 70‐year‐old woman
