Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study is an ambispective cohort study to evaluate the displacement and deformation of large brain metastases (BM) treated with magnetic resonance imaging-guided adaptive radiotherapy (MRIgART)

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

All patients had a pathologically confirmed malignant cancer and were diagnosed with brain metastases (BM) by enhanced magnetic resonance imaging (MRI) with BM volume of 2cm and above. All patients received Unity MR-linac adaptive radiotherapy. Gross tumor volume (GTV) and organs at risk (OARs) were re-delineated for every image set and analyzed for displacement and deformation.
