An observational study in Cancer, sponsored by University of Manchester. Recruiting at 1 site in United Kingdom. Open to participants aged 18 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-05-12.
Sponsored by University of Manchester · Observational
The MR BIO study aims to understand the changes in the tumour and normal tissues during a course of radiotherapy. This is accomplished by studying the MR images taken during each treatment session on the MR Linear accelerator (MR Linac). The overarching hypothesis is that changes in MR imaging and biological parameters from blood, tissue, or urine biomarkers can be measured during radiotherapy and associated with clinical outcome.
The MR Linac is a new radiotherapy machine with an on board MR scanner. This enables us to take images with high resolution and target the tumours more precisely and also reduce the dose to normal tissues. All patients undergoing treatment in the MR Linac at the Christie hospital will be considered for enrolment regardless of tumour site being treated.
The study participants will receive the standard of care treatment for their disease condition. In addition, they will be requested to give weekly blood and urine samples during the course of radiotherapy and at first follow up. On completion of radiotherapy treatment, the participants will continue to be on standard of care follow up protocol with the treating oncologist.
A small cohort of ten healthy volunteers will also be recruited to the study to develop and select some of the MR sequences only; they will not provide blood or urine samples. The healthy volunteers will be scanned for no more than one hour per session for a maximum of two sessions in total. These optimised sequences can then be used in the patient cohort.
10,818 studies on the registry are indexed under Neoplasms; 2,324 are open to participants now.
This study's planned enrollment of 250 is above the median of 200 across 2,638 observational studies indexed under Neoplasms.

Be willing and able to provide written consent. Over 18 years of age. Undergo and satisfy MRI Safety Screening Patient volunteers must be under the care of a clinical oncologist at The Christie NHS Foundation Trust and be planned to receive radiotherapy to the target site to be imaged.
Patient volunteers must be able to give blood and/or urine sample as required through the treatment period.
Non-patient (healthy) volunteers must have no known or suspected significant medical condition.
Exclusion Criteria:
The following apply to both patients and healthy volunteers:
Any conditions that would be a to MRI including:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Undertake MR Imaging to enable development of sequences.
Provide weekly blood and urine samples during period of radiotherapy as well as additional MR images.
Correlation of biomarkers
Analysis of MR images will be performed using in-house protocols based on established mathematical modelling techniques. Pearson correlation analysis will be used to assess relationships between MRI parameters and tissue markers. For oxygen enhanced imaging, two-sample unpaired t-tests will be used to identify changes in tissue oxygen in MR images. Descriptive statistics will be presented using median and 95% confidence intervals (CI) or standard deviation (SD). In addition, Bland-Altman analysis will be performed to calculate bias and 95% limits of agreement between the two measurement techniques.
Time frame: Up to five years
Correlation with patient reported toxicity
Association of detected imaging changes with variations in patient-reported toxicity and radiotherapy response at first follow up after radiotherapy.
Time frame: Up to five years
