Fig 1. ADC and FA measurements in a 54-year-old woman with a pathologically confirmed classic meningioma arising in right frontal convexity. A, Axial contrast-enhanced T1-weighted MR image shows an enhancing mass projecting inferiorly into the right frontal lobe. Three ROIs are outlined in the enhancing tumor area, peritumoral edema, and contralateral NAWM, respectively, for measurement of

3, and ADC and FA values. FA (B) and ADC (C) maps show location of ROIs. The tumor is isointense to the cortex on axial diffusion-weighted trace image (D).
