CT (Computed Tomography) of the Brain

What is CT of the Brain?

CT (Computed Tomography) of the brain is a sophisticated imaging technique that uses X-rays and computer technology to create detailed cross-sectional images of the brain. This non-invasive diagnostic tool is invaluable for assessing various neurological conditions, offering precise insights into the structure and abnormalities of the brain.

How Does a CT Scan Work?

CT scanning combines advanced X-ray equipment with computer processing to produce highly detailed images.

• Imaging Process: Multiple X-ray beams rotate around the head, capturing images from different angles. These are processed to create cross-sectional slices of the brain.

• Contrast Enhancement: In some cases, a contrast dye is used to highlight blood vessels or specific structures, improving diagnostic accuracy.

The procedure is quick, typically lasting between 10 to 30 minutes, and is performed in a specialised radiology suite.

Conditions Diagnosed with CT of the Brain

CT brain scans are used to detect and diagnose a wide range of conditions, including:

• Trauma: Identifies skull fractures, haemorrhages, or swelling due to injury.

• Stroke: Differentiates between ischaemic and haemorrhagic strokes, enabling prompt treatment.

• Tumours: Detects brain tumours or metastases.

• Hydrocephalus: Evaluates abnormal fluid accumulation within the brain.

• Infections: Assesses abscesses or other infections affecting the brain.

• Neurological Symptoms: Investigates causes of persistent headaches, seizures, or sudden changes in mental status.

Benefits of CT Scans

CT scans offer several advantages:

• Speed: Quick imaging is critical in emergencies, such as trauma or suspected stroke.

• Detail: Provides high-resolution images of the brain, essential for accurate diagnosis.

• Accessibility: Widely available and easy to perform, making it a first-line imaging choice for many conditions.

• Non-Invasive: A safe and painless method for assessing brain health.

How is a CT Scan Administered?

The process of undergoing a CT scan is straightforward:

1. Preparation: Patients may be asked to avoid eating or drinking for a few hours before the scan if contrast dye is used.

2. Positioning: The patient lies on a motorised table, which slides into the CT scanner. The head is stabilised to ensure clear imaging.

3. Imaging: The scanner rotates around the head, capturing images. If contrast dye is used, it is administered intravenously during the procedure.

4. Completion: The procedure is completed in minutes, after which patients can typically resume normal activities.

Potential Side Effects

While CT scans are generally safe, a few considerations include:

• Radiation Exposure: Minimal radiation is used, with benefits outweighing risks in most cases.

• Contrast Reactions: Rare allergic reactions to contrast dye may occur, but these are usually mild and manageable.
