What is a CT Scan of the Head?
A Computed Tomography (CT) scan uses X-rays and computer technology to create detailed images of the head and brain. It provides more clarity than a standard X-ray and helps in diagnosing various medical conditions efficiently.
Why is a Head CT Scan Performed?
Doctors recommend a head CT scan for various reasons, including:
-
Head injuries and trauma – To check for fractures, internal bleeding, or swelling.
-
Stroke detection – Helps identify blood clots or hemorrhages in the brain.
-
Brain tumors – Detects abnormal growths or masses.
-
Infections and inflammation – Identifies conditions like meningitis or encephalitis.
-
Hydrocephalus – Evaluates fluid buildup in the brain.
-
Chronic headaches and dizziness – Investigates underlying neurological causes.
The CT Scan Procedure
-
Preparation: Patients may need to remove jewelry or metallic objects. In some cases, contrast dye is administered for better imaging.
-
Positioning: The patient lies on a motorized table, which slides into the CT scanner.
-
Scanning Process: X-ray beams rotate around the head, capturing multiple images.
-
Completion: The procedure typically takes 5-10 minutes, and results are reviewed by a radiologist.
Are There Any Risks?
