Figure 1. Glioblastoma, left basal ganglia. T₁ weighted image (a) low signal intensity of the cystic component and post-contrast T₁ weighted image (b) peripheral enhancement after contrast material administration. Diffusion-weighted MR image (c) low signal intensity, typical lesion. Apparent diffusion coefficient (ADC) map (d) depicts high signal intensity of the lesion, ADC value is 2.82 x 10^–3 mm² s^–1.
