Name of the Procedure:

Magnetic Resonance Angiography (MRA) without contrast, chest (excluding myocardium)

Summary

Magnetic Resonance Angiography (MRA) without contrast is a non-invasive imaging procedure used to visualize the blood vessels in the chest. It utilizes magnetic fields and radio waves to generate detailed images without the need for contrast dye.

Purpose

The MRA aims to diagnose and evaluate conditions related to blood vessels in the chest, such as blockages, aneurysms, or abnormalities. The expected outcome is an accurate diagnosis to guide further treatment or intervention.

Indications

• Unexplained chest pain
• Suspected aortic aneurysm
• Symptoms suggesting vascular abnormalities
• Assessment of known vascular diseases

Preparation

• Follow specific dietary restrictions, if any, as advised by your healthcare provider.
• Wear loose, comfortable clothing and remove any metal objects.
• Inform your doctor of any implanted medical devices.
• You may need to undergo preliminary diagnostic tests, such as blood tests or an ECG.

Procedure Description

1. The patient lies on an examination table that slides into the MRI machine.
2. Movement must be minimized to ensure clear images.
3. The technician will use a special coil to help capture the images.
4. The MRI machine will generate magnetic fields and radio waves to create detailed images of the chest’s blood vessels.

5. Typically, no contrast dye is injected.

   The procedure requires no anesthesia or sedation in most cases unless the patient has severe claustrophobia.

Duration

The procedure typically takes between 30 to 60 minutes.

Setting

MRA is performed in a hospital or outpatient imaging center equipped with MRI technology.

Personnel

• Radiologist
• MRI Technologist
• Sometimes, a nurse for patient preparation

Risks and Complications

• Small risk if you have metal implants or claustrophobia
• Rare allergic reactions to materials used in the machine
• Possible discomfort from lying still for extended periods

Benefits

• Non-invasive with no radiation exposure
• Detailed images of blood vessels assist in accurate diagnosis
• Immediate results that can be used for further treatment plans

Recovery

• No significant recovery time; patients can usually resume normal activities immediately.
• Follow any specific instructions given by your healthcare provider.

Alternatives

• CT Angiography: Uses X-rays and contrast dye, faster, with a small amount of radiation exposure.
• Conventional Angiography: More invasive, needing catheter insertion, but offers high detail.
• Ultrasound: Less detailed, but useful for certain vascular conditions.

Patient Experience

• The patient might feel a bit of discomfort from staying still.
• The MRI machine produces loud noises; earplugs or headphones are often provided.
• Post-procedure, patients can expect to go about their day normally, with no recovery needed.
