Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults over 18 years old who are undergoing radiotherapy at The Christie NHS Foundation Trust and can provide consent.

Probably not a fit

Patients with contraindications to MRI or those unable to tolerate MR scans may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

The MR-BIO study investigates how tumors and normal tissues change during radiotherapy by utilizing high-resolution MR imaging from an MR Linear accelerator. Participants receiving standard care at The Christie NHS Foundation Trust will provide weekly blood and urine samples throughout their treatment. The study aims to correlate these imaging and biological changes with clinical outcomes, enhancing the precision of cancer treatment. This observational study includes all patients treated with the MR Linac, regardless of tumor site.

Why it matters

Potential benefit: If successful, this study could lead to improved targeting of tumors and reduced damage to normal tissues during radiotherapy.

How similar studies have gone: Other studies utilizing advanced imaging techniques in radiotherapy have shown promising results, suggesting potential for success in this novel approach.
