Định Nghĩa và Ý Nghĩa của "diffusion-weighted imaging"

What is "diffusion-weighted imaging"?

Diffusion-weighted imaging (DWI) is a type of MRI scan that helps see how water molecules move within tissues. By tracking the movement of water, this imaging technique provides detailed information about tissue structure and can help detect abnormalities. DWI is commonly used to identify conditions such as strokes, tumors, and other changes in tissue condition. It is particularly useful in evaluating areas of the brain and other soft tissues where normal water movement might be affected.
