Understanding CT / CAT Scan
A CT scan, also known as a CAT (Computed Axial Tomography) scan, is a non-invasive diagnostic test that uses X-rays and computer processing to create detailed cross-sectional images of the body. It helps healthcare professionals diagnose a wide range of conditions by giving clear views of bones, organs, blood vessels, and tissues.
What is a CT / CAT Scan?
A CT scan involves lying still on a motorised table that moves through a circular scanner. Multiple X-ray images are taken from different angles and combined using advanced software to form detailed internal pictures. It’s commonly used to detect or monitor:
Brain injuries
Tumours or cancer
Lung, liver, and abdominal issues
Fractures or internal bleeding
Cardiovascular conditions
Infections and inflammation
Some scans may involve the use of a contrast dye for better image clarity.
What to Expect from a CT / CAT Scan
Here’s what typically happens during a CT scan:
A consultation or referral is provided by your GP or specialist
You’ll lie on a scanner table that slides into the CT machine
The procedure is painless and takes about 10–30 minutes
You may need to hold your breath briefly for clearer images
If a contrast dye is used, it will be administered orally or intravenously
Results are reviewed by a radiologist and sent to your doctor
You can return to most normal activities shortly after the scan.
