GBM resectability prediction
Periventricular location
If tumour is located within 10mm of the ventricles
Associated oedema
If hypointensity extended >10mm from the tumour
Bilateral location
If tumour extends into corpus callosum
Largest diameter
If largest diameter of tumour >40mm
Eloquent location
If tumour extended into motor or sensory cortex, language cortex, insula, or basal ganglia
% chance of complete resection
