What is a CT Abdomen and Pelvis?
A CT (computed tomography) scan of the abdomen and pelvis is an advanced imaging test that uses X-rays and computer processing to produce detailed cross-sectional images of internal organs, blood vessels, and soft tissues. It is widely used to evaluate abdominal pain, suspected inflammation, infection, tumours, trauma, and complications affecting the digestive, urinary, and reproductive systems.
CT Enterography, a variation of this scan, provides highly detailed images of the small bowel. It involves drinking a specialised contrast solution to improve visualisation of the intestine and is commonly used to investigate Crohn’s disease or unexplained small bowel symptoms.
When is a CT Abdomen and Pelvis Recommended?
Doctors may recommend this test in the following situations:
- Persistent or severe abdominal pain
- Suspected infection, inflammation, or appendicitis
- Evaluation of kidney stones or urinary obstruction
- Investigation of suspected tumours or cancer spread
- Assessment of injury after trauma
- Monitoring inflammatory bowel disease (CT Enterography)
How is a CT Abdomen and Pelvis Performed?
The scan is carried out in a radiology department and typically takes 10 to 20 minutes. Patients lie on a motorised table that moves through the scanner while X-ray images are taken. Contrast dye may be given orally, intravenously, or both, depending on clinical need. CT Enterography requires drinking a large volume of contrast solution before scanning to highlight the small intestine.
What to Expect during Recovery after the Test?
Most people resume normal activities immediately after the scan. If intravenous contrast was used, increased fluid intake is encouraged to help flush it from the body. Temporary bloating or nausea from oral contrast may occur but resolves quickly.
What are the Risks of a CT Abdomen and Pelvis?
Possible risks include:
- Exposure to a small dose of radiation
- Allergic reaction to contrast dye
- Temporary kidney stress in susceptible individuals
What are the Benefits of a CT Abdomen and Pelvis?
Clinical benefits include:
- Rapid and accurate assessment of abdominal conditions
- Detailed images of internal organs and vessels
- Essential for emergency diagnosis and surgical planning
- CT Enterography offers superior imaging of the small bowel
