Question

If the main tissue of interest is the lung tissue for a CT exam, which would be the most appropriate window level setting?

a) 50
b) 0 or the level of water
c) - 600
d) 400

Answer 1

The most appropriate window level setting for CT exams of lung tissue is -600.

Step-by-step explanation:

The most appropriate window level setting for CT exams of lung tissue would be -600. The window level setting in CT imaging refers to the grayscale level that determines the brightness of the image. Since the main tissue of interest is the lung tissue, which contains air, the window level setting needs to be adjusted to adequately visualize the lung tissue.

The density of air in the lungs is much lower than water or other tissues in the body. The selected window level setting should be adjusted to display the lung tissue as a shade of gray, while allowing other tissues to be visualized as well. In CT imaging, a lower window level setting, such as -600, is commonly used to properly visualize the lung tissue.
