The aim of this study was to empirically test the effect of chemotherapy-induced tissue changes in a glioma model as measured by several diffusion indices calculated from nonmonoexponential formalisms over a wide range of b-values. We also compared these results to the conventional two-point apparent diffusion coefficient calculation using nominal b-values. Diffusion-weighted imaging was perfor...

Abstract Background Papilledema is optic disc pathology characterized by swelling of the occurring secondary to elevated intracranial pressure (ICP), and it was proposed that ICP transferred along subarachnoid space nerve (ON) leading metabolic process interruptions MRI changes within ON head. This study aimed rule out if DWI ADC map can be used as a diagnostic tool for detection papilledema va...
