To view bone, the window level is set at about 250 HU with a wide window width (1000 HU). For soft-tissue structures, a level of 50 HU and a width of 250 HU are selected. For air-filled structures (e.g. lung) a level −600 HU and a width 1000 HU are used.
What is soft tissue window?
A soft tissue window is used to view most organs. A soft tissue window cannot be used for lung parenchyma, as lung density (−500 HU) is outside range and will appear completely black.
What are the windows in CT?
The window level (WL), often also referred to as window center, is the midpoint of the range of the CT numbers displayed. When the window level is decreased the CT image will be brighter and vice versa.
