A, T2-weighted MR image shows a grade III glioma. B, Postgadolinium axial T1-weighted image does not show obvious tumor contrast enhancement. C, FA map shows that the tumor has a warmer color tone (light green [arrow]) compared with that in Fig 2. Maximum FA, minimum FA, FA range, and maximum SD are 0.170, 0.0794, 0.0906, and 0.0507, respectively. Each value of the measurements for this grade III tumor is correspondingly larger than that for the grade II tumor shown in Fig 2.
