Noncontrast cranial CT is widely and rapidly available and often serves as the initial imaging evaluation. It can aid in diagnosing the following:

  • A new area of ischemia or infarction

  • Old areas of ischemia

  • Intracranial mass, such as tumor

  • Intracranial bleeding, such as subdural hematoma or intracerebral hemorrhage
