Early target volume dynamics during MR-guided radiotherapy for glioblastoma: first results from the prospective MARGA-I trial.
BACKGROUND Serial MRI during radiotherapy may enable early response assessment and guide adaptive treatment strategies; however, data on intratreatment volumetric changes remain limited. We herein report results of the MARGA-I-study, investigating target volume changes during MR-linac-based radio-(chemo-)therapy. MAT...
