Radiology Practice Test

What is an indication that would necessitate a brain CT scan?

1. Routine check-up for neurological health

2. Suspected intracranial hemorrhage

3. Management of chronic headaches

4. Anxiety and depression assessment

The correct answer is: Suspected intracranial hemorrhage

A brain CT scan is particularly indicated when there is a suspicion of intracranial hemorrhage. This imaging modality is essential in emergency settings as it provides rapid visualization of the brain and helps to identify acute bleeding, such as subdural or intracerebral hematomas. In cases of head trauma, sudden onset headaches, or neurological deficits, a CT scan can quickly assess for any life-threatening conditions that require prompt intervention. Routine check-ups for neurological health, management of chronic headaches, and assessments of anxiety and depression do not typically warrant an immediate brain CT scan as the first-line diagnostic tool. These conditions are generally evaluated through clinical history, physical examination, and possibly other non-invasive assessments before considering imaging studies.
