Understanding Head (Brain) CT Scans
A Brain CT (Computed Tomography) scan is a diagnostic imaging procedure that uses a combination of X-rays and computer technology to produce detailed images of the brain. This type of scan provides more detailed information than standard X-rays, allowing for the visualisation of soft tissues, blood vessels, and bones in various parts of the head.
Purpose and Benefits of a Brain CT Scan
The primary purpose of a Brain CT scan is to diagnose and monitor various conditions affecting the brain and surrounding structures. The benefits of this scan include its ability to quickly provide detailed images, which is crucial in emergency situations. It is also minimally invasive and can be performed relatively quickly. The scan can help in planning medical, surgical or radiation treatment.

- Brain tumours
- Haemorrhages
- Stroke

Further Information on the Service
Scan Procedure
A CT Brain scan involves the patient lying on a table that slides into a CT scanner, which is a large, doughnut-shaped machine. The scanner rotates around the head, capturing multiple images from different angles, which a computer then compiles into cross-sectional views of the brain.
Preparation for the Scan
Patients may be advised to avoid eating or drinking for a few hours before the scan. They should wear comfortable, loose-fitting clothing and remove any metal objects that could interfere with the imaging.
What to Expect on the Day
The procedure typically lasts only a few minutes, and patients may experience a brief sensation of warmth or hear whirring noises from the machine. There are generally no side effects, but some patients may feel claustrophobic inside the scanner.
After the Scan
Post-scan, there are usually no special instructions, and patients can resume normal activities. Results are typically available within a few days and will be communicated by the referring doctor or a radiologist.
Alternative Imaging Options
Other imaging options include MRI, PET, and ultrasound scans, each with its own indications based on the patient's symptoms and the consultant's recommendation.
