What is this trial about?
Radiation therapy using the MR-Linac is used when tumors need to be treated with particularly high precision while minimizing damage to the surrounding healthy tissue as much as possible. The aim of this study is to determine whether a novel combination of magnetic resonance imaging and radiation therapy—the so-called MR-Linac—can be reliably used in everyday clinical practice. Adult patients for whom radiation therapy is medically necessary and who have no contraindications to an MRI scan are eligible to participate.

Detailed description
The current standard treatment for many types of cancer consists of conventional radiation therapy, for which computed tomography (CT) is usually used for planning. However, the image quality of CT is inferior to that of magnetic resonance imaging (MRI), especially when it comes to soft tissue. The MR-Linac system could significantly improve the precision of treatment. It combines two devices: an MRI scanner for high-resolution imaging and a linear accelerator for irradiating tumors. What makes this system unique is that precise images of the tumor can be taken immediately before and during radiation therapy. This allows the radiation to be adjusted very precisely, which could better spare the surrounding healthy tissue and reduce side effects.
The goal of this study is to investigate whether treatment using MR-Linac can be reliably implemented in everyday clinical practice (feasibility study). The study will assess whether at least 85% of the planned treatments, lasting 1 to 7 weeks, can be carried out. All patients will receive treatment with MR-Linac as part of the study. There is no follow-up observation.
Eligible participants include women and men aged 18 and older with various types of tumors, such as prostate cancer, breast cancer, rectal or esophageal cancer, head and neck tumors, liver tumors, or brain tumors. Patients who require palliative radiation therapy (which is not intended to cure the disease) may also participate. Treatment is provided exclusively using the new MR-Linac device at the University Hospital of Tübingen. Individuals with contraindications for an MRI (e.g., severe claustrophobia or certain metal implants) as well as pregnant women are excluded.
