FCI-Glioblastoma Study

The goal of this study is to test if a new type of MRI scanner, called Field-Cycling Imaging (FCI), can tell the difference between tumour growth (progression) and 'pseudo-progression' (which looks like tumour but is not cancerous tissue) in patients with glioblastoma. The main question it aims to answer is: • Can FCI differentiate glioblastoma progression from pseudo-progression? Participants will undergo a standard MRI scan and an FCI scan, three times during the study. One before starting adjuvant chemotherapy, another one after three cycles and one at the end of treatment.
