Cerebral cortical restricted diffusion or gyriform restricted diffusion refers to curvilinear hyperintense signal involving the cerebral cortex on DWI images with a corresponding low signal on ADC images.
Causes include:
- vascular thrombo-occlusive disease (most common) 1
- hemodynamic changes
- infections
- metabolic
- others
