iRADIOLOGY, EarlyView.This systematic review assessed radiomics‐based studies for predicting treatment response in brain metastases, evaluating their predictive performance and radiomic quality score (RQS) adherence. Radiomic models demonstrated superior predictive performance outperforming the clinical and visual assessment, with further improvement when clinical features ...

Journal of Magnetic Resonance Imaging, EarlyView.ABSTRACT Conventional MRI is limited in imaging tissues with short T2 relaxation times, such as bone, ligaments, and cartilage, due to their rapid signal decay. This limitation has spurred the development of specialized MRI techniques designed specifically for short‐T2 tissue imaging.

Radiosurgery for Vestibular Schwannomas
Journal of the Chinese Medical Association, 2005 Radiosurgery has been established as an important alternative to microsurgery. We report our experience with radiosurgery for tumor control and the complications of unilateral vestibular schwannomas.We reviewed our early experience regarding clinical presentation, management and outcomes in 45 patients with acoustic schwannomas who underwent gamma ...

Journal of Magnetic Resonance Imaging, EarlyView.ABSTRACT Background Tumor characterization and treatment efficacy are associated with tissue hypoxia. MR‐derived oxygen extraction fraction (OEF) may offer valuable tumor insights but depends on multiple measurement parameters, often requiring multiple sequence acquisitions.

Dose-Escalated Robotic SBRT for Stage I-II Prostate Cancer
Frontiers in Oncology, 2015 : Stereotactic body radiotherapy (SBRT) is the precise external delivery of very high-dose radiotherapy to targets in the body, with treatment completed in one to five fractions. SBRT should be an ideal approach for organ-confined prostate cancer because

Three Dimensional Expansion of Margins for Single-fraction Treatments: Stereotactic Radiosurgery Brain Cases [PDF]
arXiv, 2012 Purpose: To derive a clinically-practical margin formula between clinical target volume (CTV) and planning target volume (PTV) for single-fraction stereotactic radiosurgery (SRS).Methods: In previous publications on the margin between the CTV and the PTV, a Gaussian function with zero mean was assumed for the systematic error and the ma-chine ...

Hypofractionation Utilisation in Radiation Therapy: A Regional Department Evaluation
Journal of Medical Radiation Sciences, EarlyView.This study has validated the increase of hypo fractionated treatments over a range of cancer sites and treatment intents, with increased treatment complexity over a decade (2012, 2019, 2022). This has a direct impact on both the departmental resources and patient‐centred care, offering value‐based radiotherapy.

A kinetic model of tumor growth and its radiation response with an application to Gamma Knife stereotactic radiosurgery [PDF]
arXiv, 2015 We developed a mathematical model to simulate the growth of tumor volume and its response to a single fraction of high dose irradiation. We made several key assumptions of the model. Tumor volume is composed of proliferating (or dividing) cancer cells and non-dividing (or dead) cells.
