Hypervision Proton Surgery: The Future Direction of Proton Therapy

iNew Medicine, EarlyView.
ABSTRACT Proton beams provide unique physical advantages characterized by a low entrance dose, negligible exit dose, and a sharp Bragg peak, which enable superior sparing of normal tissues and support safe dose escalation for improved tumor control. However, conventional photon‐based fractionation remains widely used in proton therapy, where prolonged ...

Workflow to detect exceeded dose constraints in pancreatic stereotactic body irradiation after intrafraction motion during magnetic resonance-guided adaptive radiotherapy using a deep learning-refined contour propagation tool

Physics and Imaging in Radiation Oncology
Introduction: The adapt-to-shape (ATS) process on the MR-Linac involves manual contour edits followed by treatment plan re-optimization on daily pre-beam MRIs.

Going beyond the borders : field-of-view extension in MR/PET hybrid imaging [PDF]

, 2012
The recent combination of Magnetic Resonance Imaging (MRI) and Positron Emission Tomography (PET) is of emerging interest in clinical routine. On the one hand, MRI is a widely-used diagnostic tool in medical practice.

Functional Imaging for Identification of Functionally Critical Brain Regions to Spare in Glioma Radiation Therapy Planning: A Systematic Review

Journal of Medical Radiation Sciences, EarlyView.
This review highlights the role of functional imaging in sparing cognitive brain regions during glioma radiotherapy. It shows promising dose reduction without compromising target coverage, but evidence remains limited, requiring standardisation and prospective validation.

Prognostic Value of Combined FDG PET and MRI Analysis of Cervical Cancer: A Systematic Review and Meta‐Analysis

Journal of Medical Radiation Sciences, EarlyView.
This systematic review and meta‐analysis synthesised FDG PET/MRWE biomarkers in cervical cancer, including a pooled analysis of the association between metabolic activity (SUV‐based metrics) and tumour diffusion characteristics (ADC measures). Prognostic evidence from the included studies was also analysed to identify PET‐ and MRI‐based parameters, as ...

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

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 ...

Dosimetric effect of abdominal compression in online adaptive planning for abdominal cancers treated with a 1.5 Tesla magnetic resonance-guided linear accelerator

Physics and Imaging in Radiation Oncology
Compression belts (CBs) are sometimes used to reduce respiratory motion during stereotactic body radiotherapy of abdominal cancers with magnetic resonance (MR)-guided online adaptive planning. This study evaluated the dosimetric effects of overriding the

Intraoperative Evaluation of Sarcoma Surgical Margins With Indocyanine Green Fluorescence Imaging: Results From an Observational Study

Journal of Surgical Oncology, EarlyView.
ABSTRACT Introduction Sarcomas are rare malignancies that affect both adults and children. Surgical removal with negative histopathological margins is the foundation of sarcoma treatment. Failure to achieve negative margins puts patients at risk of local recurrence (LR). LR rates range between 10% and 30%.
