UNDERSTANDING CT SCAN windowing
This document discusses CT scan window settings and how adjusting the window width and level can optimize images for different tissues. It explains that window width determines the range of gray shades and window level sets the midpoint. Narrowing the width increases contrast while widening it decreases contrast. Raising the level darkens images while lowering it lightens them. The document then describes recommended window settings for various tissues like soft tissue, bone, lungs, brain and their benefits for evaluation. It highlights that the stroke window setting is particularly useful for detecting subtle hypo densities that may indicate stroke.
