Brief Summary:
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:
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.
