CT abdomen and pelvis is a common scan for belly pain, infection, stones and tumours. Learn what it shows, how to prepare and when contrast is needed.
A CT abdomen and pelvis scan takes detailed pictures from the lower chest to the pelvis. It helps doctors find the cause of belly pain, infection, stones, bleeding, tumours and bowel problems, and is often done with contrast for better detail.
What Does This Scan Show?
The scan covers the liver, spleen, pancreas, kidneys, bowel, bladder, reproductive organs, lymph nodes and blood vessels. Because it shows all of these in one visit, it is a good test when the cause of pain is not clear. It can also show fluid collections, abscesses and bleeding. See what a CT scan is.

- Severe or lasting stomach pain
- Fever with belly tenderness, to look for abscess or appendicitis. See CT for appendicitis
- Suspected stones or blood in urine. See CT KUB
- Unexplained weight loss or a lump
- Cancer staging and follow-up
- After surgery or injury to check for complications
Contrast: Is It Needed?
Most CT abdomen scans use intravenous contrast, and some also need an oral contrast drink. Contrast shows blood supply and helps separate normal from abnormal tissue. A plain scan may be enough for stones. Kidney function is checked before contrast. Read CT scan with contrast.
How to Prepare
- Fast for 4 to 6 hours if contrast is planned.
- You may be asked to drink 1 to 2 glasses of oral contrast over an hour or two.
- Carry your creatinine report and previous scans.
- Tell the staff about diabetes, kidney disease, allergy and pregnancy.
Full steps are in CT scan preparation.
What Happens During the Scan?
You lie on your back on the table. After oral contrast and a cannula for IV contrast, the table moves through the ring. You may need to hold your breath for a few seconds. The scan takes only minutes, and the visit about 30 to 60 minutes with oral contrast. See CT scan procedure.
A Practical Example
Rohit, 28, has pain in the right lower belly, fever and vomiting. The ultrasound is not clear. A CT abdomen and pelvis shows an inflamed appendix, and he is taken for surgery the same day. In another case, a 60-year-old with weight loss has a CT showing a pancreatic mass, which allows early specialist referral. In both, the CT gave a quick and full view.
Quick Summary
- Covers the belly and pelvis in one scan
- Often uses contrast, with kidney checks
- Finding the cause of pain, infection, stones and tumours
- Scan takes minutes; visit takes under an hour
What If the Report Shows Something Unclear?
Radiology reports sometimes mention small cysts, minor fluid or tiny nodes that are common and harmless. Phrases such as "likely benign" or "advise follow-up" mean the radiologist wants your doctor to watch the finding. If something needs more detail, your doctor may ask for an ultrasound, MRI or a repeat CT after some weeks. Avoid searching the internet and worrying before you meet your doctor. Bring your previous scans, since comparing images often settles the question quickly. See how to read a CT scan report.
After the Scan: Care Tips
Drink plenty of water, especially if contrast was used, and eat normally. Report any rash, swelling, severe abdominal pain or fever to your doctor. Keep your CD and report safe for future comparison.
