In a CT scan, window width and window level are parameters that control the brightness and contrast of the images. The window level determines the midpoint of the range of CT numbers (Hounsfield units) displayed, while the window width defines the range of CT numbers that will be shown. A narrow window width increases contrast, highlighting subtle differences in tissue density, whereas a wider window width provides a more uniform image, useful for viewing broader areas of density. Adjusting these settings helps radiologists better visualize specific anatomical structures or pathologies.
