To Determine Whether it is Feasible to Treat Patients Requiring Urgent Radiotherapy Diagnosed With Metastatic Cord Compression (MSCC) on the Magnetic Resonance Linear Accelerator (MRL) in a Single Appointment and Compare it to the Standard of Care Radiotherapy Pathway

The goal of this clinical trial is to understand whether the Magnetic Resonance Linear Accelerator (MRL) could expedite Radiotherapy treatment for Metastatic Cord Compression (MSCC) by removing the need for a planning CT (pCT) scan prior to treatment. Radiotherapy will be delivered in one appointment on the MRL and compared to the standard of care of two appointments: a CT scan and a Radiotherapy appointment. The main questions it aims to answer are: * Can the MRL deliver successful treatment of MSCC in a single 1-hour appointment? * Can the MRL treat participants within 24 hours from the doctor's decision to treat? * Did it take less time from consent to completion of treatment when patients were treated on the MRL? * Do the questionnaire scores reflect satisfaction with treatment on the MRL? Researchers will compare treatment on the MRL in one appointment to a group receiving standard of care radiotherapy in two appointments. Participants in both groups will receive the same prescription of 8Gray (Gy) in one treatment (fraction) delivered with one posterior-anterior beam as per our department policies and national standards. Participants will be asked to complete an optional questionnaire prior to treatment to monitor the diversity of the study population. This questionnaire is anonymised, no personal data that could identify a participant is collected on this questionnaire. After treatment participants will be asked to complete an experience questionnaire, to assess treatment experience. Once the questionnaire is complete active participation in the trial is no longer needed, researchers will monitor participants notes for up to 12 months after treatment to record participant well being and function.
