Diffusion-weighted imaging (DWI)

Diffusion-weighted imaging (DWI) is an MRI technique that measures the movement of water molecules within tissues. In healthy tissue, water molecules move freely, but in areas affected by issues like stroke or tumors, this movement is restricted due to cell damage or density changes. DWI captures these differences, helping doctors identify and assess abnormalities quickly and accurately. It’s particularly valuable for detecting early strokes, where rapid diagnosis can improve treatment outcomes. Overall, DWI provides detailed insights into tissue structure by visualizing how water molecules move, aiding in diagnosis and patient management.
