Axial brain images of a 40 year old female patient with a glioblastoma. A) T1-weighted post-contrast spin-echo image (TR 600 ms/TE 14 ms) shows an enhancing lesion. B) T2-weighted spin-echo image (TR 3,000 ms/TE 92 ms) shows the lesion and larger area with edema. C) The same area on the LSDI mean diffusion-weighted image (b-factor 1,000 s/mm2) appears isointense with the surrounding normal tissue. There is evidence, however, of slight deformation of the ventricle and sulcus anatomy. D) Mean diffusion coefficient map exhibits elevated diffusion both within lesion and edema. ADC measured within the green region of interest (ROI) outline for tumor (defined on the T1-weighted image) is 1.18 µm2/ms and within the red ROI outline for edema 1.35 µm2/ms. Gray and white matter show no obvious difference in diffusion and appear dark gray (ADC=0.76 µm2/ms).
