72198 Magnetic resonance angiography, pelvis, with or without contrast material(s)

Name of the Procedure:

Magnetic Resonance Angiography, Pelvis, with or without Contrast Material(s) (MRA pelvis)

Summary

Magnetic Resonance Angiography (MRA) of the pelvis is an imaging test that uses strong magnetic fields and radio waves to create detailed images of the blood vessels in the pelvic area. It can be done with or without the use of contrast material, which helps to highlight the blood vessels more clearly.

Purpose

MRA of the pelvis is used to diagnose and evaluate conditions affecting the blood vessels in the pelvic region. It helps healthcare providers assess issues such as blood vessel blockages, aneurysms, or abnormal blood flow patterns.

Indications

• Persistent pelvic pain
• Suspected blood vessel abnormalities
• History of vascular disease
• Pre-surgical assessment for pelvic procedures
• Trauma to the pelvic area

Preparation

• Patients may be asked to fast for a few hours before the procedure.
• Metal objects, including jewelry and watches, must be removed as they can interfere with the magnetic field.
• If contrast material is used, patients may need blood tests to check kidney function.
• Inform the doctor of any allergies, especially to contrast agents, and any existing medical conditions.

Procedure Description

1. The patient will lie down on the MRI table.
2. If contrast material is needed, an intravenous (IV) line will be inserted to administer the contrast.
3. The table slides into the MRI machine, which is a large, tube-shaped scanner.
4. The patient must lie still while the machine takes images, which can cause a loud noise.
5. The procedure is monitored by a technician from an adjacent room.

Duration

The procedure typically takes around 30-60 minutes.

Setting

The procedure is performed in a hospital radiology department or an outpatient imaging center.

Personnel

• Radiologists
• MRI Technologists
• Nurses (if IV contrast is used)

Risks and Complications

• Mild reactions to contrast material, such as nausea or itching
• Rarely, allergic reactions to the contrast material
• Claustrophobia during the MRI scan
• In extremely rare cases, nephrogenic systemic fibrosis if contrast is used

Benefits

• Non-invasive and does not involve radiation
• Provides detailed images of blood vessels
• Can help diagnose and treat vascular conditions early

Recovery

• Patients can usually resume normal activities immediately after the procedure.
• Drink plenty of fluids to help flush out the contrast material if it was used.
• Follow-up appointments may be scheduled to discuss results with your doctor.

Alternatives

• CT Angiography: Uses X-rays and contrast material but involves radiation exposure.
• Doppler Ultrasound: Less detailed but does not involve radiation or contrast agents.
• Conventional Angiography: Invasive, involves radiation, but may be required for detailed vessel analysis.

Patient Experience

• Patients may feel a cool sensation if contrast is administered.
• The procedure itself is painless, although the machine’s loud noises might be uncomfortable. Earplugs or headphones are typically provided.
• Some patients might feel anxious due to the enclosed space but can communicate with the technician at any time.
