A computed tomography or CT scan is a non-invasive and painless test that is conducted to obtain a precise image inside the body. Using a technology that gives more detailed images than a standard x-ray can, images produced by a CT scan includes the bones, organs and muscles that help in making accurate diagnoses. CT scans are normally requested as a more detailed procedure after a standard x-ray is performed.
You will be required to fast for 2-4 hours before the test. This is important to ensure accuracy because food ingested before a test can impact the quality of the images.
You will be required to change into a hospital gown before the procedure.
You will be asked to lie down on a table attached to a CT scanner with the portion of your body to be examined exposed. The scanner then takes x-ray images of the area, rotating and tilting to scan from different angles and positions. The images are then sent for analysis to aid in diagnosis.
The scan lasts a few seconds and you will be required to lie very still during the scan to obtain the clearest and most images possible.
In some scans, a dye-based contrast material is injected into a vein to enhance images and make it easier for diagnosis. It helps with the checking for abnormal growths and tumours, inflammation, and nerve damage.
You will be given a follow up appointment to review your test results. Should you feel unwell, contact your doctor immediately or call our 24HR Emergency Clinic.
