CT of the Abdomen/Pelvis

Your doctor has requested a computed tomography scan (CT scan or CAT scan) of your abdomen and pelvis. CT scanning uses X-ray technology and advanced computer analysis to create detailed images of your body. A CT scan of the abdomen and pelvis can help diagnose problems in the bladder, uterus, prostate, liver, or bowels.

This procedure is typically used to help diagnose the cause of abdominal or pelvic pain. It is also used to identify diseases of the internal organs such as:

• Appendicitis
• Diverticulitis
• Abscesses
• Pancreatitis
• Colitis
• Crohn’s Disease
• Cancers of the colon, liver, kidneys, pancreas, and bladder
• Kidney and bladder stones
• Abdominal Aortic Aneurysms (AAA) and other diseases of the vessels such as blood clots

CT scanning of the abdomen/pelvis is also performed to quickly identify injuries to the liver, spleen, kidneys, or other abdominal organs in cases of trauma. It can be a useful tool in surgical planning and to guide biopsies, as well as to assist in properly administering radiation treatment for tumors.

A CT scan of the pelvis can provide valuable information about various medical conditions affecting the pelvic region. It is often recommended if you have symptoms such as unexplained pelvic pain, abnormal bleeding, or issues with the bladder or reproductive organs. Additionally, a pelvic CT scan can help assess the spread of cancers and the effectiveness of treatments, identify blood flow obstructions, and detect plaque buildup in blood vessels.

While positioning you on the exam table, the technologist will explain your procedure and answer any questions you may have. If you are receiving contrast dye, it may be given through an injection in an IV placed in your arm. The contrast dye may cause you to experience a warm sensation all over your body and a metallic taste in your mouth. This is normal. If you experience any itching, sneezing, nasal congestion, scratchy throat, or swelling of your face, you should notify the technologist immediately.

Most often, you will be asked to lie flat on your back with your arms over your head. The table you are on will slide into the CT scanner. The scanner is open at the back and the front, allowing you to see out. The technologist will always be able to see and hear you during your exam. You will be asked to hold very still and at times to hold your breath. This procedure usually takes approximately 15-30 minutes.

How to Prepare:

• No solid foods 2 hours prior to your appointment time.
• Oral Prep (Readi-Cat) may be required. If so, you will need to drink the Readi-Cat 1-1/2 hours before your appointment. Try to finish the prep within a 10–15-minute timeframe.
• Medications may be taken normally, and a list should be brought to your appointment.
• If IV contrast is ordered, recent bloodwork within 90 days is required for patients over 65 years old, diabetic, or with any history of renal (kidney) disease.
• Women should always inform their physician and the CT technologist if there is any possibility that they are pregnant.
• Please inform your doctor and our technologist if you have any known allergies to contrast (dye).

The benefits of CT of the Abdomen/Pelvis:

• Can provide more detailed, accurate results than traditional X-ray.
• Can detect problems/disease earlier.
• Involves minimal risks.
• Painless, noninvasive, and accurate.
• Fast and simple.
• Can be performed if you have an implanted medical device, unlike MRI.
• May eliminate the need for exploratory surgery or biopsy.

Risks you should be aware of:

• As with any procedure, there is a slight risk of infection.
• Rarely, this procedure can cause a temporary increase in pain.
• There is a slight risk of an allergic reaction to the contrast material.
• There are risks associated with exposure to ionizing radiation. You should discuss this with your physician.

If your doctor gave you an order, please bring it with you.
