What is the white color on brain ct?
One: The skull is in the white circle. Two: And some CT images on the Internet are black. That's not a head CT, such as a chest or abdomen CT. Of course, you can't find the skull, or it's not a CT film, but an MR film. Three: there is a small eye on the white circle, which represents bone cyst or normal blood vessels, and common normal things.
