IPEM Topical Report: a national survey of MRI use for external beam radiotherapy treatment planning in the UK: 2025 IPEM survey results

Richard J. Speight, Sarah Allwood‐Spiers, Michael J. Dubec, Ben George et autres

Magnetic resonance imaging (MRI) offers superior soft tissue contrast compared to computed tomography (CT), making it highly valuable in external beam radiotherapy (EBRT) planning. However, there are a number of barriers that have limited widespread use of MRI for EBRT planning in …

Automated MR-only radiotherapy outperforms CT-based radiotherapy and decreases hands-on time for head-and-neck cancer treatment

Iris Lauwers, Marta Ewa Capala, Sandeep Kaushik, László Ruskó et autres

Introduction: Cancer incidence is expected to increase in Europe by 18% in eighteen years. To account for the increasing patient numbers, the workload per patient needs to be reduced. One step towards future-proof radiotherapy is automated MR-only radiotherapy as it could eliminate …

A combined automatic organ at risk contouring and synthetic Computed Tomography solution for pelvic Magnetic Resonance-only radiotherapy

J. Wyatt, Sandeep Kaushik, C. Cozzini, Bernadett Kolozsvári et autres

Background and Purpose: Magnetic Resonance (MR)-only radiotherapy improves treatment accuracy and efficiency but requires a synthetic Computed Tomography (sCT) for dose calculations. Automatic MR-based Organs At Risk (OARs) contouring could further improve consistency and efficiency. A combined automatic MR OAR contouring and …

Dose differences between patients treated with MR-only, CT-only, or MR-CT fusion radiotherapy for prostate cancer

J. Wyatt, Stephen Hedley, Neil D. Richmond, Serena West et autres

OBJECTIVES: Magnetic Resonance (MR)-only radiotherapy has been clinically implemented but its dose impact has not been assessed in clinical practice. This study evaluated the volume and dose differences between patients treated with CT-only, MR-CT fusion, or MR-only prostate radiotherapy pathways. METHODS: Four …

Synthetic CT generation using Zero TE MR for head-and-neck radiotherapy

Iris Lauwers, Marta Ewa Capala, Sandeep S. Kaushik, László Ruskó et autres

BACKGROUND AND PURPOSE: MRI-based synthetic CTs (synCTs) show promise to replace planning CT scans in various anatomical regions. However, the head-and-neck region remains challenging because of patient-specific air, bone and soft tissues interfaces and oropharynx cavities. Zero-Echo-Time (ZTE) MRI can be fast …

Verification imaging in prostate MR-only radiotherapy: Are fiducial markers necessary?

R. Pearson, Laura M. O'Connor, Kate Skehan, D. Redding et autres

PURPOSE/OBJECTIVE: MR-only radiotherapy planning exploits the benefits of MRI soft-tissue delineation, whilst negating the registration inaccuracies caused by MRI CT fusion. Fiducial markers have conventionally been used in prostate radiotherapy to reduce on-treatment image matching variability. However, this is an invasive procedure …

Improving the Efficiency of Single-Isocenter Multiple Metastases Stereotactic Radiosurgery Treatment

J. Wyatt, Rekha Mohanraj, Judith H. Mott

Purpose Multiple brain metastases can be treated efficiently with Stereotactic Radio Surgery (SRS) using a Single Isocenter Dynamic Conformal Arc (SIDCA) technique. Currently plans are manually optimized, which may lead to unnecessary table angles and arcs being used. This study aimed to …
