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 ...

New workflow and motion analysis for gastric mucosa-associated lymphoid tissue lymphoma on a 1.5-T MR-Linac

Technical Innovations & Patient Support in Radiation Oncology
We developed and evaluated a multiplane cine magnetic resonance imaging (MRI) workflow for magnetic resonance (MR)-guided online adaptive radiation therapy (MRgOART) for gastric mucosa-associated lymphoid tissue (MALT) lymphoma.

Sonographic localisation of lymph nodes suspicious of metastatic breast cancer to surgical axillary levels

Journal of Medical Radiation Sciences, Volume 72, Issue 1, Page 119-138, March 2025.
Sonographic imaging is used to identify the presence, number and location of malignant lymph nodes. Axillary lymph nodes suspicious of harbouring breast cancer metastasis can be localised to three surgical axillary levels. This paper will unpack the axillary anatomy, muscular sonographic landmarks, surgical axillary lymph node levels and the ...

Fast Phase-Contrast Cine MRI for Assessing Intracranial Hemodynamics and Cerebrospinal Fluid Dynamics

Diagnostics, 2020
We propose fast phase-contrast cine magnetic resonance imaging (PC-cine MRI) to allow breath-hold acquisition, and we compared intracranial hemo- and hydrodynamic parameters obtained during breath holding between full inspiration and end expiration. On a

Comparative Performance Analysis of an Open Source Motion‐Compensated Cardiac Diffusion Sequence Across Different MRI Systems and Gradient Strengths—A Pilot Study

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To validate the performance of an open‐source cardiac diffusion sequence framework and to investigate hardware‐based performance differences. Methods Three second order motion compensated sequence files were compiled using Pulseq and applied across different MRI systems to image five volunteers.

Strain‐encoded magnetic resonance: a method for the assessment of myocardial deformation

ESC Heart Failure, 2019
This study aims to assess the usefulness of strain‐encoded magnetic resonance (SENC) for the quantification of myocardial deformation (‘strain’) in healthy volunteers and for the diagnostic workup of patients with different cardiovascular pathologies ...
