Fig 6. Pre- and postsurgery DTI-based images at similar section locations for patient 2 (Table). The patient underwent ventriculoperitoneal shunt proximal revision. ADC maps before (A) and after (C) surgery show significant reduction in ventricle volume with no apparent change in ADC values. FA maps before (B) and after (D) surgery show significant reduction in FA values of the internal capsule after surgery (see enlarged color-scale images). E and F, ROI analysis for this patient before and after surgery: FA is significantly reduced after surgery (P < .001) in the internal capsule, whereas ADC values remain the same.
