Diffusion Mri in Intracranial Hypertension: Quantitative Assesment.

  The ADC values from the head of the caudate nucleus and the cortex were significantly higher in the IIH group, compared to the control group. When the ADC values of the SIH and control groups were compared, it was found that some of the ADC measurements (subcortical white matter, cortex and semioval center) were significantly different. The comparison of the IIH and the SIH groups revealed that the ADC measurements central white matter in the centrum semiovale, the subcortical white matter and the posterior leg of the internal capsule were significantly different. Conclusıons: We have found increased diffusion IIH and SIH patients, which supports the development of brain edema. Even though the mechanism of the brain edema in IIH are not entirely clear, it is thought that the mechanism is different from the brain edema caused by a mass or a sinus thrombosis.
