Name of the Procedure:

Computed Tomography (CT) Scan of the Abdomen and Pelvis without Contrast followed by Contrast; Full study.

• Common Name(s): CT scan of the abdomen and pelvis with and without contrast.
• Technical Term(s): CT Abdomen/Pelvis without & with contrast.

Summary:

A CT scan of the abdomen and pelvis uses X-ray technology to produce detailed images of these body regions. Initially, images are captured without contrast material. Subsequently, a contrast dye is administered to enhance the clarity of the images, allowing for further detailed examination of the abdominal and pelvic areas.

Purpose:

• Medical Conditions: Diagnoses abdominal pain, infection, injury, tumors, and other abnormalities.
• Goals/Outcomes: Provides detailed images to aid in the diagnosis, management, and treatment of various abdominal and pelvic conditions.

Indications:

• Unexplained abdominal or pelvic pain.
• Suspected internal injuries or infections.
• Unclear results from other imaging tests (e.g., ultrasound).
• Monitoring known conditions like tumors.

Preparation:

• Pre-procedure Instructions: Patients may need to fast (no eating or drinking) for a few hours prior to the procedure.
• Additional Tests: Blood tests to check kidney function, given the use of contrast material.

Procedure Description:

1. Initial Scanning: Patient lies on a motorized table that slides into the CT scanner. Initial images are taken without any contrast material.
2. Administration of Contrast: Contrast material is administered, usually via an intravenous (IV) injection.
3. Further Imaging: Once the contrast is administered, additional images are taken to provide a more detailed view.
   • Equipment Used: CT scanner, IV line for contrast.
   • Anesthesia: Generally not required, but patients need to remain still.

Duration:

Typically, 30-60 minutes.

Setting:

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

Personnel:

• Radiologist.
• Radiologic technologist.
• Nursing staff, if necessary, for IV placement and patient monitoring.

Risks and Complications:

• Common: Slight discomfort from IV insertion, mild allergic reactions to contrast material.
• Rare: Severe allergic reactions, kidney issues in patients with pre-existing kidney problems.

Benefits:

• Provides detailed and precise images.
• Can help detect and diagnose a variety of conditions, aiding in effective treatment planning.
• Results are generally available fairly quickly.

Recovery:

• Post-procedure Care: Patients can usually resume normal activities immediately.
• Instructions: Stay hydrated to help flush contrast material from the body.
• Follow-up: Based on findings, additional tests or consultations may be scheduled.

Alternatives:

• Ultrasound: Non-invasive but may provide less detail.
• MRI: No radiation but more time-consuming and expensive.
• Basic X-rays: Less detailed images.

Patient Experience:

• Patients may feel a warm sensation or slight discomfort during the contrast injection.
• Generally painless, though staying still can be challenging for some.
• Any discomfort is usually minimal and brief.

Pain management and comfort measures are usually not necessary due to the non-invasive nature of the procedure.
