Comparative Evaluation of Four Stereotactic Radiosurgery Planning Approaches for Treatment of Posterior Choroidal Melanoma

Journal of Medical Radiation Sciences, EarlyView.
This study evaluated four stereotactic radiosurgery planning approaches for posterior choroidal melanoma (CM). Analysis of thirteen CM cases resulted in a clinically meaningful reduction in dose to the brain for Brainlab Elements modulated arcs (BE) and Varian Eclipse HyperArc modulated arcs (HA) compared to Brainlab iPlan dynamic conformal arc therapy

Optimising hypoxia PET imaging and its applications in guiding targeted radiation therapy for non‐small cell lung cancer: a scoping review

Journal of Medical Radiation Sciences, Volume 72, Issue 1, Page 106-118, March 2025.
This review article reports that quantification of hypoxic volumes using PET in the pre‐radiation therapy setting is of prognostic value and indicative of treatment response in non‐small cell lung cancer. Abstract Introduction Non‐small cell lung cancer (NSCLC) is the leading cause of cancer‐related death. Definitive treatment includes chemotherapy and

Translation of dynamic contrast-enhanced imaging onto a magnetic resonance-guided linear accelerator in patients with head and neck cancer

Physics and Imaging in Radiation Oncology
Background and purpose: Magnetic resonance imaging – linear accelerator (MRI-linac) systems permit imaging of tumours to guide treatment. Dynamic contrast enhanced (DCE)-MRI allows investigation of tumour perfusion.
