Name of the Procedure:

Computed Tomography (CT) Scan of the Abdomen and Pelvis without Contrast Material
Common names: Abdominal CT, Pelvic CT.

Summary

A CT scan of the abdomen and pelvis without contrast material is a non-invasive imaging test that uses X-ray technology to create detailed pictures of the abdominal and pelvic organs. This scan does not involve the injection of contrast dye.

Purpose

This procedure is used to diagnose and evaluate various medical conditions within the abdomen and pelvis, including injuries, infections, tumors, and other abnormalities. It aims to provide detailed information to help guide diagnosis and treatment plans.

Indications

• Unexplained abdominal pain
• Suspected tumors or cancers
• Kidney stones
• Appendicitis
• Internal bleeding
• Bowel obstructions
• Chronic abdominal conditions

Preparation

• Fasting may be required for several hours before the procedure.
• Patients should inform their healthcare provider of any medications they are taking, as some may need to be discontinued.
• Remove any metal objects, such as jewelry, to avoid interference with imaging.

Procedure Description

1. The patient lies on a motorized table that slides into the CT scanner.
2. The scanner is a large, doughnut-shaped machine that rotates around the patient, taking multiple X-ray images from different angles.
3. The patient must remain still during the scan to ensure clear images.
4. The entire process is monitored by a radiology technician from an adjacent room.

Duration

The procedure typically takes about 10 to 30 minutes.

Setting

Performed in a hospital radiology department or an outpatient imaging center.

Personnel

• Radiology technician (operates the CT scanner)
• Radiologist (interprets the images)
• Nursing staff (assists with patient preparation and care)

Risks and Complications

• Exposure to a small amount of radiation, though generally considered safe.
• Potential discomfort from lying still during the procedure.
• Rarely, a reaction to prescribed medication if given.

Benefits

• Provides detailed images for accurate diagnosis.
• Non-invasive and relatively quick.
• Helps guide further treatment plans.

Recovery

• No significant recovery time; patients can generally resume normal activities immediately.
• Follow-up appointments may be scheduled to discuss results with a healthcare provider.

Alternatives

• MRI (Magnetic Resonance Imaging) of the abdomen and pelvis: Offers detailed images but takes longer and may not be suitable for patients with certain implants.
• Ultrasound: Non-radiative but may not be as detailed for certain conditions.
• X-ray: Less detailed than a CT scan.

Patient Experience

• Patients may feel cold due to air conditioning in imaging rooms.
• The table may be hard, and staying still can be uncomfortable.
• Noise from the machine can be heard during the scan.
• Pain management is generally not necessary, as the procedure is painless.
