- Rectal Contrast: Utilized less commonly, this is administered as an enema for specific pelvic scans to visualise the lower bowel.

Popular Questions
How long does it take to get CT scan results in the UK?

Essential Pre-Scan Instructions from Your Healthcare Provider

These steps aren’t recommendations; they are thoroughly designed to help the machine take the most precise pictures possible. If you miss them, the images might come out fuzzy.

Dietary Restrictions and Fasting
For scans of your abdomen or pelvis, you’ll probably need to go without eating. That typically means no food for four to six hours beforehand.

Always check your letter for the exact timing, as it can differ.
Medication and Health Conditions
Provide your medical team a full list of every pill and supplement you take. Most of the time, you can keep taking essential medicines with a tiny sip of water even while abstaining from food. But some drugs need particular handling. Diabetes medications like Metformin or blood-thinners are common examples. You must also notify them about any allergies, kidney issues, or if there’s any possibility you could be pregnant. This information is vital for your safety, especially if a contrast agent is used.
