For glioblastoma (GBM) patients it has been proven that a [18F]FET-PET scan is very helpful especially in target volume definition and after the treatment, in turn, the combination of MRI and [18F]FET-PET is diagnostically most useful to distinguish between radiation necrosis and a real progressive disease.
The response to therapy is based on the newly formulated Revised Assessment in Neuro-Oncology (RANO) criteria. Kinetic and static [18F]FET-PET scans are useful to supplement this modality and its own prognostic value concerning relapsing patients will be examined.
The special feature of this study is the use of both modalities in parallel, allowing simultaneous acquisition of morphological changes, functional and molecular imaging.
Secondary methodological issues are dealt with, such as the relationship between contrast uptake, perfusion and [18F]FET uptake. In this regard, the hybrid imaging may serve for hypothesis generation, as in parallel in a unique way of contrast enhancement and tracer kinetics can be investigated (simultaneous contrast-enhanced analysis and tracer application).
In particular, FET kinetics are examined in more detail (for example, differences between increasing and decreasing kinetics) to find ways of how to use certain MRI sequences for better visualization of viable tumor tissue and vice versa .
