Overview
A CT (computed tomography) scan of the abdomen and pelvis is a special type of X-ray that takes detailed pictures of the inside of your belly and pelvic area. It uses a large machine that rotates around you to create cross-sectional images, like slices of your body. This helps doctors see organs, blood vessels, bones, and tissues clearly.
Key facts
A CT abdomen pelvis scan is painless and usually takes about 10 to 30 minutes.
You may be asked to drink a liquid contrast agent or receive an injection to make certain organs show up better on the images.
The scan uses a small amount of radiation, which is generally safe for most people, but it is not recommended during pregnancy unless absolutely necessary.
Yes, CT scans of the abdomen and pelvis are very common. They are often used to help diagnose a wide range of conditions, from kidney stones to infections or injuries.
This scan is used for people of all ages who have abdominal or pelvic symptoms, such as pain, swelling, or unexplained weight loss. It may also be used for cancer staging, trauma evaluation, or to guide certain procedures.

Causes
Main causes
Doctors may order a CT abdomen pelvis scan to investigate the cause of pain, bleeding, or other symptoms in the belly or pelvic area.
It is used to check for conditions like appendicitis, diverticulitis, kidney stones, or tumors.
It can help evaluate the spread of cancer (staging) or guide a biopsy (taking a small tissue sample).
Risk factors
Older age (some abdominal conditions become more common with age)
Having a history of cancer or inflammatory bowel disease
Certain lifestyle factors like smoking or heavy alcohol use
Obesity (increases risk of gallstones, fatty liver disease, etc.)
When to see a doctor
See a doctor urgently if:
If you have sudden, severe abdominal or pelvic pain that won't go away.
If you are vomiting blood or have blood in your stool or urine.
If you have a high fever along with belly pain.
If you were in a serious accident and have belly pain.
Book a routine appointment if:
If you have ongoing, mild to moderate abdominal symptoms that last more than a few days.
If you have unexplained weight loss or changes in bowel habits.
If you have a known condition (like Crohn's disease) that needs monitoring.
Many causes of abdominal or pelvic discomfort are not serious and can be treated easily. However, if you are worried about your symptoms, it is always best to see a doctor. They can decide if a CT scan or another test is right for you.
Diagnosis
A CT abdomen pelvis scan is one of many imaging tests used to help diagnose conditions. The images are reviewed by a radiologist, a doctor specially trained in reading scans. The results are then sent to your regular doctor or specialist, who will use them along with your symptoms and other test results to make a diagnosis.
Tests that may be done
CT scan of the abdomen and pelvis (with or without contrast agent)
Blood tests and urine tests to check for infection, inflammation, or organ function
Ultrasound or MRI in some cases, especially if radiation is a concern
What to expect at your appointment
Before the scan, you may be asked to not eat or drink for a few hours. You will lie on a narrow table that slides into the CT machine. The machine will rotate around you and take pictures. You may be asked to hold your breath for a few seconds. If contrast is needed, you will receive an injection in your arm or be asked to drink a liquid. The scan is painless and you can usually go home right after.
Treatment
Treatment depends entirely on what the CT scan finds. It could be antibiotics for an infection, pain relief for kidney stones, or further tests and surgery for more serious conditions. Your doctor will discuss the results with you and create a plan that is right for your specific situation.
Self-care at home
Follow all preparation instructions for the scan, like fasting or drinking contrast.
After the scan, drink plenty of water if you received contrast to help flush it out (unless your doctor says otherwise).
If you have symptoms, rest, use over-the-counter pain relief (if safe for you), and monitor your symptoms.
Medical treatments
Medical treatments are based on the condition found. For example, infections may be treated with antibiotics, inflammation may be managed with anti-inflammatory medications, and conditions like kidney stones may be treated with medications to help pass them or with procedures like lithotripsy. Always follow your doctor's advice about any prescribed treatments.
When is surgery considered?
Surgery may be needed for conditions like a burst appendix, a blocked bowel, or certain cancers. Your doctor will explain if surgery is an option and what it involves.
Living with this condition
If a condition is found on your CT scan, your daily life may need adjustments. For example, if you have a chronic condition like Crohn's disease or diverticulitis, you may need to avoid certain foods, take medications regularly, and have regular check-ups. If no serious condition is found, you can return to your normal routine.
Lifestyle tips
Eat a balanced diet rich in fiber to support digestive health.
Stay hydrated by drinking plenty of water throughout the day.
Get regular exercise to maintain a healthy weight and reduce stress.
Avoid smoking and limit alcohol to lower your risk of many abdominal conditions.
Diet and exercise
A healthy diet with plenty of fruits, vegetables, and whole grains can help prevent many digestive problems. Aim for at least 30 minutes of moderate exercise most days, like walking or swimming. If you have a specific condition, your doctor or a dietitian can offer personalized advice.
Mental health and emotional wellbeing
Waiting for test results or living with a chronic condition can be stressful or worrying. It is normal to feel anxious. Talking to family, friends, or a counselor can help. If you feel overwhelmed, reach out to a mental health professional.
Prevention
Many conditions that require a CT scan cannot be prevented entirely, but you can reduce your risk by maintaining a healthy lifestyle, avoiding smoking, limiting alcohol, and managing chronic conditions like high blood pressure or diabetes. Some cancers can be detected early through screening, which may help.
Vaccines
Vaccines are not directly related to CT scans, but staying up-to-date on vaccines (like for hepatitis B or HPV) can reduce your risk of certain liver or cervical cancers that might later require imaging.
Screening programmes
Screening tests like colonoscopy for colon cancer, or ultrasound for AAA (abdominal aortic aneurysm) in certain groups, can detect problems early before symptoms develop. Your doctor can tell you which screenings are appropriate for you based on your age and risk factors.
Complications
If left untreated
If the condition found on CT is not treated, it could worsen. For example, an infection might spread, a kidney stone could cause kidney damage, or a cancer could grow.
Delaying treatment for a burst appendix or a blocked bowel can lead to life-threatening complications.
Untreated chronic conditions may cause lasting damage to organs like the kidneys or liver.
Long-term outlook
The outlook depends on what is found. Many conditions are treatable and have a good outcome if caught early. CT scans are powerful tools that help doctors find problems quickly, which often leads to better results. Even for serious conditions like cancer, early detection and treatment can improve outcomes. Your healthcare team will guide you through the next steps and support you along the way.
