Role of diffusion weighted imaging, apparent diffusion coefficient and magnetic resonence perfusion among acute ischemic stroke patient.

Acute ischemic stroke requires quick identification of infarct core and salvageable tissue for proper management. MRI techniques, including diffusion-weighted imaging (DWI), apparent diffusion coefficient (ADC) mapping and MR perfusion, provide essential early physiologic information. A study conducted at Santosh Medical College Hospital involved 60 patients presenting within 24 hours of neurological symptoms. The results showed DWI and ADC reliably detected restricted diffusion, while MR perfusion highlighted perfusion abnormalities. The findings enhance stroke evaluation by demonstrating the importance of combining diffusion and perfusion imaging to better understand stroke pathophysiology, potentially improving patient outcomes.
