What does a brain CT scan examine?

Skull lesions: Brain CT can be used to observe the structure and morphology of the skull, identifying skull fractures, dislocations caused by trauma, as well as other abnormalities in skull structure and shape, such as craniovertebral junction anomalies or skull defects. Vascular lesions: For conditions such as cerebral infarction and intracerebral hemorrhage, brain CT can reveal high-density or low-density lesions within the cranium, aiding in accurate diagnosis. It can also detect traumatic intracranial hematomas. Brain tissue lesions: Brain CT imaging allows evaluation of brain atrophy, including its location and severity, which assists in diagnosing diseases such as Alzheimer's disease and cerebral ischemia. It also helps assess treatment efficacy and disease severity.
