Generation of 3D reference dosimetric datasets towards adoption of model‐based dose calculations for permanent implant prostate brachytherapy

Medical Physics, Volume 53, Issue 2, February 2026.
Abstract Purpose This work aims to create and validate a comprehensive set of test cases and 3D reference dosimetric datasets for model‐based dose calculation algorithms (MBDCAs) in permanent implant prostate brachytherapy. These test cases address the limits of the standard TG‐43 formalism towards improving dose evaluations in prostate cancer ...

Melanoma of the Choroid and Ciliary Body in Children: Remission of Metastatic Melanoma of the Choroid After Treatment With Chemotherapy and Immune Checkpoint Inhibition

Pediatric Blood &Cancer, Volume 73, Issue 2, February 2026.
ABSTRACT Background Uveal melanoma is the most common malignant primary intraocular tumor in adults, associated with high mortality. Pediatric uveal melanoma generally has a more favorable course. However, when metastasis occurs, therapeutic options are limited.

Brachytherapy, A viable option of globe salvage in treatment of large ciliary body melanocytoma

Indian Journal of Ophthalmology, 2014
We report a case of large histopathologically proven melanocytoma of the ciliary body in a 15-year-old male, presented with rapid extraocular growth following incisional biopsy with scleral patch graft.

Nanobiotechnology‐Based Approaches for Uveal Melanoma Treatment

SmartMat, Volume 7, Issue 1, February 2026.
Emerging platforms for uveal melanoma combine precision drug delivery, ROS‐amplifying modalities, and nucleic acid transport to overcome ocular barriers and immunosuppressive niches. Targeted nanoparticles, virus‐like constructs, and injectable depots enable localized activation, controlled release, and gene‐level reprogramming.

Use of brachytherapy in children with cancer: the search for an uncomplicated cure [PDF]

, 2006
Brachytherapy is a sophisticated radiation method in which radioisotopes are placed inside or at a short distance from the tumour. The volume of tissue that receives the prescribed dose of radiotherapy is therefore fairly small compared

Two-year angiographic and intravascular ultrasound follow-up after implantation of sirolimus-eluting stents in human coronary arteries [PDF]

, 2003
BACKGROUND: The safety and efficacy of sirolimus-eluting stenting have been demonstrated, but the outcome of patients treated with this novel technology beyond the first year remains unknown.

Quantifying stent‐induced dose perturbations in intravascular brachytherapy using 3D‐ printed phantoms and film dosimetry

Journal of Applied Clinical Medical Physics, Volume 27, Issue 1, January 2026.
Abstract Background Coronary artery disease (CAD), the leading cause of death worldwide, is the narrowing of coronary arteries due to atherosclerotic plaque buildup. A common treatment for CAD is percutaneous coronary intervention (PCI), often involving stent placement. However, a common complication or in‐stent restenosis (ISR) can occur in 10%–20% of

A dosimetry evaluation of 90y-stent implantation in intracoronary radiation treatment [PDF]

, 2013
Ionizing particles have been used for the treatment of atherosclerosis. Internal irradiation is commonly carried out by means of several methods (catheter-based systems, radioactive stents or balloons) to reduce the probability of restenosis. 90Y, due

Ocular Ultrasound in Clinical Practice: Diagnostic Applications, Pitfalls, and Future Directions

Clinical Neuroimaging, Volume 3, Issue 1, 2026.
ABSTRACT Ocular ultrasound (OUS) has become an essential diagnostic modality, enabling noninvasive imaging of intraocular and orbital structures. OUS is particularly valuable in emergency medicine, ophthalmology, and critical care, facilitating rapid diagnosis of acute vision loss and other systemic diseases. This review covers the ultrasound technique,
