In a CT scan, the cortex appears as a grayish structure. This is because CT imaging uses X-rays to produce images, and different tissues in the body absorb X-rays to varying degrees, resulting in differences in the shades of gray seen on the image. The cortex, which is the outer layer of the brain, has a density that is intermediate between that of the brain parenchyma and the surrounding cerebrospinal fluid, resulting in a gray appearance.
