Do I need to prepare for a CT scan?

For most CT scans, no special preparation is needed. However, if your scan uses contrast dye (a liquid that highlights internal structures), you’ll be advised to avoid eating or drinking for about 4–6 hours before your appointment.

You should wear comfortable, loose clothing and remove any metal items such as jewellery, belts, or watches. Always tell the clinic if you have allergies, kidney issues, or are pregnant, as this can affect scan preparation or contrast use.

Your radiographer will guide you through the process on arrival. The scan itself usually takes 10–20 minutes.
