-Head CT scans are often used to diagnose brain tumor.  A [[CT scan will usually show a nonhomogeneous mass with a hypointense center and a variable ring of enhancement surrounded by [[edema]]. Part of a [[lateral ventricle]] is usually deformed, and both lateral and [[third ventricle]]s may be displaced.It can confirm the location of the [[cancer]] and show the surroundings nearby, as well as [[lymph node]]s and distant organs where the cancer might have spread. These are helpful for determining the stage of the cancer and in determining whether [[surgery]] is a good treatment option. CT scans can also be used to guide biopsy and a biopsy sample is usually removed and looked at under a microscope.
