Name of the Procedure:

Magnetic Resonance Angiography (MRA) of the Upper Extremity, with or without contrast material(s).

Summary

Magnetic Resonance Angiography (MRA) of the upper extremity is a non-invasive imaging test that uses magnetic resonance imaging (MRI) to visualize the blood vessels in the arms. The procedure can be done with or without the use of contrast material to enhance the images.

Purpose

MRA of the upper extremity is used to diagnose and evaluate abnormalities in the blood vessels of the arms, such as blockages, aneurysms, or vascular malformations. The goal is to provide detailed images that can aid in the diagnosis and guide treatment planning.

Indications

• Symptoms such as pain, numbness, or weakness in the arms
• Suspected vascular disease or abnormalities
• Pre-surgical planning or post-surgical evaluation
• Monitoring known vascular conditions

Preparation

• Patients may be instructed to avoid eating or drinking for a few hours before the procedure if contrast material is used.
• Removal of all metal objects, as they can interfere with the MRI machine.
• Inform the healthcare provider about any allergies, kidney problems, or claustrophobia.
• Pre-procedure imaging studies or blood tests might be required.

Procedure Description

1. The patient lies on a movable table that slides into the MRI machine.
2. If contrast material is used, it will be injected into a vein in the arm.
3. The patient must remain still while the machine takes images.
4. The machine uses magnetic fields and radio waves to capture detailed pictures of the blood vessels.
5. The procedure is typically painless, although some patients may feel mildly uncomfortable due to the enclosed space.

Duration

The procedure usually takes about 30 to 90 minutes, depending on whether contrast material is used and the complexity of the images required.

Setting

MRA of the upper extremity is performed in a hospital's radiology department or an outpatient imaging center.

Personnel

• Radiologist
• MRI technologist
• Nurse (if contrast material is administered)

Risks and Complications

• Rare allergic reaction to contrast material
• Mild discomfort or anxiety from the MRI machine's enclosed space
• Very rare risk of kidney problems if contrast material is used

Benefits

• Detailed images of blood vessels without the need for invasive procedures
• Helps in accurate diagnosis and treatment planning
• No exposure to ionizing radiation

Recovery

• Most patients can resume normal activities immediately after the procedure.
• Drink plenty of fluids to help flush the contrast material from your body, if used.
• Follow any additional instructions given by your healthcare provider.

Alternatives

• CT Angiography (CTA)
• Conventional Angiography
• Doppler Ultrasound
• Each alternative has its own pros and cons, such as varying degrees of detail and radiation exposure.

Patient Experience

• Patients may feel a cool sensation if contrast material is injected.
• Some patients may experience anxiety due to the confined space of the MRI machine.
• The procedure is generally well-tolerated, and the imaging process itself is painless.
• Earplugs or headphones may be provided to reduce noise from the MRI machine during the procedure.
