This multicenter retrospective study evaluated the effects of a time delay and steroids on the volume of peritumoral edema (VPTE) in dogs with extra-axial brain tumours. The hypothesis is that VPTE will decrease between the diagnostic (MRI-1) and RT planning (MRI-2) MRIs following the administration of steroids. Inclusion required paired MRI acquisitions within 3 months, with VPTE contouring for each MRI registered to the RT planning CT. No edema was defined as < 0.2 cm
