Post-treatment changes of tumour perfusion parameters can help to predict survival in patients with high-grade astrocytoma.

Objectives: Vascular characteristics of tumour and peritumoral volumes of high-grade gliomas change with treatment. This work evaluates the variations of T2*-weighted perfusion parameters as overall survival (OS) predictors.

Methods: Forty-five patients with histologically confirmed high-grade astrocytoma (8 grade III and 37 grade IV) were included.
