Name of the Procedure:

    Common Name: Magnetic Resonance Angiography (MRA) without Contrast, Abdomen
    Medical Term: HCPCS Code C8901 - Magnetic resonance angiography without contrast, abdomen

Summary

Magnetic Resonance Angiography (MRA) without contrast of the abdomen is a non-invasive imaging procedure that uses powerful magnets and radio waves to produce detailed images of the blood vessels and blood flow in the abdominal area. This technique does not require the use of a contrast agent.

Purpose

    - Detecting abnormalities in abdominal blood vessels, such as aneurysms, blockages, or malformations.
    - Monitoring conditions like atherosclerosis or vascular anomalies.
    - Guiding treatment plans for conditions affecting abdominal vasculature.

Indications

    - Unexplained abdominal pain.
    - Suspected aneurysms or vascular malformations.
    - Symptoms of vascular diseases such as claudication or rest pain.
    - History of conditions like atherosclerosis or chronic mesenteric ischemia.

Preparation

    - Follow any specific dietary restrictions as advised by your doctor.
    - Inform your healthcare provider about any metal implants, pacemakers, or other medical devices.
    - You may need to remove jewelry, watches, or any other metal objects before the procedure.

Procedure Description

    1. Upon arrival, you will change into a hospital gown and lie down on the MRI scanner table.
    2. The table slides into the MRI machine, and you'll need to stay still during the scan.
    3. The machine creates a magnetic field and sends radio waves through your body to capture images.
    4. The procedure is monitored by a technologist from an adjacent room, maintaining communication with you.
    5. No anesthesia or sedation is typically required as this is a non-invasive procedure.

Duration

    - The entire procedure usually takes about 30-60 minutes.

Setting

    - Performed in a hospital radiology department, outpatient imaging center, or specialized diagnostic facility.

Personnel

    - Radiologist
    - MRI Technologist
    - Supporting medical staff as needed

Risks and Complications

    - Minimal risks as no radiation or contrast dye is used.
    - Rare potential for discomfort from lying still.
    - Claustrophobia (fear of confined spaces) for some patients.

Benefits

    - Provides detailed images of blood vessels without exposure to radiation or contrast agents.
    - Aids in accurate diagnosis and treatment planning.
    - Non-invasive and typically painless.

Recovery

    - No specific post-procedure care needed.
    - Patients can resume normal activities immediately unless otherwise advised.
    - Follow-up appointments as necessary based on the results.

Alternatives

    - CT Angiography (CTA) - involves x-ray and contrast dye.
    - Ultrasound - may be less detailed for certain vascular structures.
    - DSA (Digital Subtraction Angiography) - invasive and uses contrast dye.
    - Each alternative has its pros and cons which should be discussed with your healthcare provider.

Patient Experience

    - Most find the procedure comfortable; however, some may feel claustrophobic.
    - Communication maintained with the technologist minimizes anxiety.
    - Noise-canceling headphones or earplugs may be provided to block out MRI machine sounds.
    - No significant pain expected during or after the procedure.
