Additional Diagnostic Value of Unenhanced Computed Tomography plus Diffusion-Weighted Imaging Combined with Routine Magnetic Resonance Imaging Findings of Early-Stage Gliblastoma

Figure 1

Magnetic resonance and computed tomography images of the brain. (a) Axial T1-weighted, (b) axial T2-weighted, (c) fluid-attenuated inversion recovery (FLAIR), (d) diffusion-weighted, and (e) contrast-enhanced magnetic resonance images display a poorly demarcated lesion in the right temporal and occipital lobe. The lesion shows hypointensity to isointensity on T1-weighted imaging and inhomogeneous hyperintensity on T2-weighted and FLAIR imaging with diffuse perilesional edema. The diffusion-weighted image shows an isointense lesion with a hyperintense region (arrowhead). Postcontrast magnetic resonance imaging shows no enhancement. (f) Axial-view head-window unenhanced computed tomography image of the head shows a hyperattenuated region (arrow).
