What this trial studies

The MOMENTUM study is an international registry that collects data on patients undergoing radiation therapy using the MR-Linac technology. This observational cohort study aims to enhance the implementation of MR-guided radiation therapy, which allows for real-time imaging and precision treatment. By gathering technical and clinical data, the study seeks to optimize treatment outcomes, minimize side effects, and improve overall patient survival and quality of life. Participants include cancer patients aged 18 and older who are receiving treatment or imaging on the MR-Linac machine.

Who should consider this trial

Good fit: Ideal candidates are cancer patients aged 18 and older who are scheduled for treatment or imaging on an MR-Linac machine.

Not a fit: Patients with MRI contraindications, such as those who are pregnant or have incompatible metal implants, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved survival rates and reduced side effects for cancer patients undergoing radiation therapy.

How similar studies have performed: Other studies have shown promise with MR-guided radiation therapy, indicating potential for success in this innovative approach.
