Name of the Procedure:

Magnetic Resonance Angiography (MRA) with Contrast, Chest (Excluding Myocardium)
HCPCS Code: C8909

Summary

Magnetic Resonance Angiography (MRA) with contrast is a non-invasive imaging procedure that uses magnetic fields and contrast material to create detailed images of the blood vessels in the chest, excluding the heart muscle. This helps doctors evaluate various conditions affecting the chest’s vascular system.

Purpose

This MRA procedure aims to diagnose and evaluate vascular conditions, such as blockages, aneurysms, or abnormalities in the blood vessels within the chest cavity. The goal is to provide a clear and detailed view of these structures to aid in accurate diagnosis and treatment planning.

Indications

• Unexplained chest pain
• Suspected vascular abnormalities or aneurysms
• Blockages or narrowing of blood vessels
• Monitoring known vascular conditions
• Pre-surgical planning for vascular procedures

Preparation

• Patients may be asked to fast for 4-6 hours before the procedure.
• Patients should inform their doctor of any allergies, particularly to contrast material.
• Any metal implants or electronic devices should be discussed with the doctor.
• Blood tests may be performed beforehand to ensure kidney function is adequate for contrast material.

Procedure Description

1. The patient lies on an MRI table, which slides into the MRI machine.
2. An intravenous (IV) line is inserted to administer the contrast material.
3. The patient must remain still as the machine generates images using magnetic fields.
4. The contrast agent is injected midway through the procedure for enhanced imaging.
5. The patient may hear loud noises from the machine and will be provided with ear protection.
6. Communication with the technologist is maintained through an intercom.

Duration

The procedure typically takes about 30 to 60 minutes.

Setting

The MRA with contrast is commonly performed in a hospital radiology department or an imaging center equipped with MRI technology.

Personnel

• Radiologist
• MRI Technologist
• Nurse (for IV insertion and patient preparation)

Risks and Complications

• Allergic reaction to the contrast material (rare)
• Kidney function impairment (for patients with pre-existing kidney issues)
• Claustrophobia or discomfort due to lying still in the MRI machine
• Mild discomfort at the IV site

Benefits

• Provides detailed images of the chest’s vascular structures, aiding in accurate diagnosis.
• Non-invasive with no exposure to ionizing radiation.
• Helps in early detection and treatment planning of vascular conditions.

Recovery

• Patients can usually resume normal activities immediately after the procedure.
• Hydration is advised to help flush out the contrast material.
• Follow-up instructions will be provided based on the specific findings.
• Any discomfort at the IV site typically resolves quickly.

Alternatives

• CT Angiography: Uses X-rays to provide detailed images but involves radiation exposure.
• Doppler Ultrasound: Non-invasive but less detailed than MRA.
• Conventional Angiography: Invasive, involving catheter insertion, but offers direct intervention options.

Patient Experience

• The patient will need to lie still and may experience some discomfort from the IV insertion.
• Loud noises from the MRI machine are common; ear protection is provided to minimize distress.
• Some patients may feel warmth when the contrast is injected.
• Any anxiety or discomfort related to the procedure can typically be managed with reassurance and communication with the healthcare team.
