Description of CT Small Bowel Series (CT Enterography)
CT Enterography is an advanced, non-invasive imaging technique that provides high-resolution images of the small intestine and surrounding abdominal organs. It is more detailed than a standard abdominal CT scan and is particularly useful for diagnosing inflammatory bowel diseases such as Crohn’s disease.
During the test, patients drink a specially prepared contrast solution that gently distends the small bowel, making the intestinal walls easier to visualise. An intravenous contrast injection is also administered to highlight blood vessels and inflamed tissues. Together, these techniques allow radiologists to detect swelling, ulcers, strictures, fistulas, infections, bleeding, or tumours.
CT Enterography offers superior visualisation of the small bowel compared with routine CT and is often preferred when capsule endoscopy or MRI enterography is inconclusive or unsuitable. It is also useful for identifying complications of Crohn’s disease, such as abscesses or penetrating disease.
At Advicon Imaging, we use state-of-the-art multidetector CT scanners to obtain detailed images rapidly and safely. Our experienced team ensures patient comfort throughout the preparation, drinking phase, and scanning process. All Medicare-eligible studies are fully bulk-billed.
Frequently Asked Questions
What is a CT Small Bowel Series / CT Enterography?
It is a specialised CT scan that uses oral and IV contrast to produce detailed images of the small intestine.
Why has my doctor ordered this scan?
Common reasons include suspected Crohn’s disease, abdominal pain, unexplained diarrhoea, bleeding, blockages, or abnormal findings on other tests.
Do I need preparation?
Yes.
- You will be asked to fast for several hours.
- You will drink an oral contrast solution over 45–60 minutes before the scan.
- Inform us if you have kidney disease, diabetes, thyroid issues, or past contrast reactions.
- Remove metal around your abdomen.
What happens during the scan?
After drinking the oral contrast, you will lie on the CT table. An IV contrast injection is administered, and the scan is performed. You may be asked to hold your breath briefly.
Is the scan painful?
No. The scan is painless, although drinking the contrast may feel uncomfortable due to fullness.
Does this scan involve radiation?
Yes, but modern scanners minimise radiation while maintaining excellent image quality.
Will I need contrast?
Yes. Both oral contrast (to distend the bowel) and IV contrast (to highlight inflammation and blood vessels) are typically required.
How long does the appointment take?
The total process takes about 1.5 hours, including drinking time. The scan itself takes only a few minutes.
Can I drive afterwards?
Yes. You may return to normal activities immediately unless otherwise instructed.
When will my doctor receive the results?
