Head CT Scan: Uses, Procedure, and What to Expect

A head CT (computed tomography) uses X-rays and computer processing to create detailed cross-sectional brain images. It diagnoses:

• Brain tumors
• Head injuries
• Stroke
• Aneurysms
• Sinus/ear infections
• Dental problems

Procedure

Painless, <30 minutes. Patient lies on a table; scanner rotates around head, capturing X-rays from multiple angles. Computer reconstructs detailed images.

Valuable for rapid, accurate diagnosis of neurological and structural conditions.
