Explanation

"High b-value DWI" refers to a specific type of imaging used in MRI scans. The "b-value" is a setting that affects how sensitive the scan is to the movement of water molecules in the body. When the b-value is high, the scan is more sensitive to this movement, which can help to highlight certain types of tissue or abnormalities. "DWI" stands for "Diffusion Weighted Imaging", a technique that uses this sensitivity to water movement to create detailed images of the body's internal structures.
