Figure 5. MRI and diffusion weighted imaging(DWI) from a patient with low-grade oligodendrogliomas. (a) T1 weighted image. (b) T2 weighted image. (c) DWI (b = 1000). (d) Apparent diffusion coefficient (ADC). The tumour exhibited inhomogeneous with various increase of signal intensity on both T2 weighted image and DWI.
