What is a CT Scan?
A CT scan (Computed Tomography scan) is a fast and painless medical imaging test that uses X-rays and advanced computer technology to create detailed pictures of the inside of your body. It helps doctors see bones, organs, blood vessels, and soft tissues more clearly than a standard X-ray, allowing for accurate diagnosis and treatment planning. Most CT scans are completed within minutes, making them a convenient and effective way to investigate a wide range of health concerns.
What happens during a CT Scan?
During a CT scan, you will lie comfortably on a padded scanning table that moves slowly through a large, doughnut-shaped scanner. The scan is quick and non-invasive.
To help produce clear images, you may be asked to keep still and briefly hold your breath during parts of the examination. In some cases, a contrast dye may be given through a small injection into a vein, usually in your arm, to help highlight certain organs, tissues, or blood vessels.
A qualified radiographer will guide you throughout the process, and most scans are completed within minutes.
Do I need to do any prep?
For some CT scans, you might be required to drink some water before your appointment helps us obtain clearer, more detailed images.
Water may be used to:
- Improve image quality by gently filling the stomach, bowel, or bladder.
- Help visualise organs more clearly, particularly in the abdomen and pelvis.
- Support hydration, especially when IV contrast is required.
The amount of water needed varies depending on the scan. Our team will provide specific instructions when your appointment is booked.
