New MRI method aims to sharpen prostate cancer treatment for patients with hip replacements
NCT ID NCT07042256
First seen Jun 27, 2026 · Last updated Jul 07, 2026 · Updated 2 times
Summary
This study looks at whether a special low-field MRI scanner can give clearer images for prostate cancer radiation therapy in people who have both hips replaced. Standard MRI often creates blurry images around metal implants, making it hard to aim the radiation precisely. The researchers will test a system where patients are scanned in a low-field MRI and then moved to a radiation machine without changing position, hoping to improve treatment accuracy and reduce side effects. About 13 adults with localized prostate cancer and bilateral hip prostheses will take part.

Inclusion Criteria: * Diagnosis of localized prostate cancer suitable for definitive SBRT based on a multidisciplinary tumour board recommendation and / or clinical practice guideline. * Presence of bilateral hip prostheses labeled as MR safe or MR-conditional. * ECOG performance status ≤ 2. * Signed informed consent. * Age ≥18 years - Exclusion Criteria: * Large body size that would not fit into the MRI-simulator bore * Hip prosthesis that are labeled as MR unsafe; * Contraindications to MRI including but not limited to: * Claustrophobia unmanageable by sedation * Electronic devices such as pacemakers, defibrillators, deep brain stimulators, cochlear implants that are labeled as MR unsafe, electronic devices labeled as MR safe or MR conditional are not a contraindication; * Metallic foreign body in the eye or aneurysm clips in the brain; * Clinically significant concomitant diseases that would interfere with the study (e.g. hepatic dysfunction, cardiovascular disease). * Inability to follow the procedures of the study, e.g. due to language problems, psychological disorders, dementia, etc. * Enrolment of the investigator, his/her family members, employees and other dependent persons.
