Cardiac CT Scan
What is a CT scan?
CT stands for Computerised Tomography. A CT scan uses X-rays and a computer to create detailed 3D images of the heart and blood vessels. It is particularly useful for looking at the coronary arteries and the structure of the heart and lungs.
Why is a CT test done?
A CT scan provides more detailed information than a standard X-ray or ultrasound. It helps in planning surgeries or interventions by providing a precise "roadmap" of the anatomy.
What happens during the test?
Your child will lie on a flat bed which passes through the scanner. The scanner is shaped like a giant doughnut. It is important to lie very still. Most cardiac CT scans require an injection of "dye" (contrast) into a vein to make the blood vessels show up clearly.
How long does it take?
The actual scan takes only a few seconds, but the preparation and positioning take about 15-20 minutes.
Does it hurt?
The scan itself is painless. If a contrast injection is needed, it involves a small needle prick. Some children may need sedation or a general anaesthetic if they are very young or unable to lie still.
DR NAQVI'S TOP TIPS for having a CT scan
- Wear comfortable clothing without metal zips or buttons.
- If contrast is being used, your child may be asked not to eat for a few hours before the test.
- The scanner makes a whirring noise but is not as noisy as an MRI.
