Name of the Procedure:

Magnetic Resonance Angiography with Contrast, Abdomen (C8900) Common names: MRA of the Abdomen with Contrast, Abdominal MRA

Summary

Magnetic Resonance Angiography (MRA) of the abdomen with contrast is a non-invasive imaging test that uses a magnetic field, radio waves, and a contrast material to create detailed images of the blood vessels in the abdominal area.

Purpose

This procedure is used to diagnose and evaluate conditions affecting abdominal blood vessels, such as aneurysms, blockages, or abnormalities. The goal is to provide clear images of blood flow and vessel structure, helping to plan appropriate treatment.

Indications

• Symptoms like severe abdominal pain, blood in urine, or unexplained weight loss.
• Known or suspected vascular diseases such as an aneurysm or arterial stenosis.
• Pre-surgical evaluation for procedures involving blood vessels.
• Follow-up on previously diagnosed conditions.

Preparation

• Patients may be required to fast for 4-6 hours before the procedure.
• Inform your doctor of any medications or allergies, especially to contrast dye.
• Remove all metal objects and wear a hospital gown.

Procedure Description

1. The patient lies on a movable examination table.
2. An intravenous (IV) line is inserted to administer the contrast material.
3. The table slides into the MRI machine, and images are taken using magnetic fields and radio waves.
4. The contrast dye highlights the blood vessels, creating detailed images.
5. The procedure is painless but may involve a slight warmth or tingling sensation when the contrast dye is injected.

Duration

The procedure typically takes between 30 to 60 minutes.

Setting

It is usually performed in a hospital's radiology department or an outpatient imaging center.

Personnel

• Radiologist: Specializes in interpreting medical images.
• MRI Technologists: Operate the MRI machine and assist the patient.
• Nurses: Manage the IV line and administer contrast dye if needed.

Risks and Complications

• Allergic reactions to contrast dye (rare).
• Slight risk of kidney damage, especially in patients with pre-existing kidney conditions.
• Claustrophobia or discomfort from lying still.

Benefits

• Non-invasive with no need for catheter insertion.
• No exposure to ionizing radiation.
• Highly detailed images of blood vessels and blood flow.

Recovery

• Most patients can return to normal activities immediately after the procedure.
• Drink plenty of fluids to help flush out the contrast material.
• Follow any specific instructions given by your healthcare provider.

Alternatives

• CT Angiography (CTA): Uses X-rays and contrast dye but involves radiation exposure.
• Ultrasound: Less detailed for blood vessels but no radiation exposure.
• Conventional Angiography: More invasive and involves catheter insertion directly into blood vessels.

Patient Experience

During the procedure, patients may feel a slight warmth or tingling from the contrast dye. The MRI machine makes loud noises, so ear protection is provided. Post-procedure, some may experience minor discomfort at the IV site, but pain is minimal and can be managed with over-the-counter pain relief if necessary.
