77046 Magnetic resonance imaging, breast, without contrast material; unilateral

Name of the Procedure:

Magnetic Resonance Imaging (MRI) of the Breast, Unilateral (without contrast material)
Commonly referred to as Breast MRI without contrast, Unilateral MRI.

Summary

A Breast MRI without contrast is a non-invasive imaging procedure used to create detailed pictures of the breast tissue. This scan uses magnetic fields and radio waves to produce high-resolution images, helpful in examining the breast for abnormalities without the use of contrast dye.

Purpose

The procedure is designed to:

• Detect and evaluate breast abnormalities such as lumps or masses.
• Assist in monitoring changes in the breast over time.
• Provide detailed images for better diagnosis and treatment planning.
• Offer an alternative for patients who cannot undergo contrast-enhanced MRI.

Indications

• Unexplained breast pain or lumps.
• Family history of breast cancer.
• Following up on previously identified breast abnormalities.
• Pre-surgical planning.
• Patients with implants that make mammograms less effective.

Preparation

• Patients may need to wear loose, comfortable clothing and avoid wearing any metal objects due to the magnetic fields.
• There are generally no dietary restrictions; fasting is not required.
• All metallic items, including jewelry, piercings, or dental work that could affect the MRI should be removed.
• An initial mammogram or ultrasound might be requested by the physician.

Procedure Description

1. The patient lies face down on a special table equipped with openings for the breasts.
2. The table slides into the MRI machine, which is a large tube containing powerful magnets.
3. The MRI machine makes a series of loud noises as it takes images; earplugs may be provided to reduce discomfort.
4. The patient must remain still during the scan to ensure clear images are captured.
5. The procedure does not involve any needle sticks or contrast injections.

Duration

The procedure typically takes about 30 to 45 minutes, but may vary depending on specific requirements.

Setting

The procedure is commonly performed in an outpatient imaging center or a hospital's radiology department.

Personnel

• A radiologic technologist conducts the MRI scan.
• A radiologist interprets the MRI images.
• Nursing staff may assist as needed.

Risks and Complications

• The MRI procedure itself is generally safe, but some patients may feel claustrophobic inside the MRI machine.
• There are no radiation risks as MRI uses magnetic fields.
• Rarely, issues may arise for individuals with certain implants or metal objects in the body.

Benefits

• High-resolution images provide a clear view of breast tissue and any abnormalities.
• Non-invasive with minimal risk involved.
• No exposure to ionizing radiation.
• Can be repeated as necessary for monitoring changes over time.

Recovery

• No recovery time is required; patients can resume normal activities immediately after the procedure.
• Follow-up appointments may be scheduled to discuss MRI results with a healthcare provider.

Alternatives

• Mammography: Uses X-rays but may not provide as detailed images.
• Ultrasound: Useful for certain types of breast tissue but may require additional imaging for thorough examination.
• Contrast-enhanced MRI: Provides more detailed images but involves the use of a contrast dye.

Patient Experience

During the MRI, the patient may hear loud, repetitive noises and might feel slight pressure from lying still for an extended period. Comfort measures include earplugs or headphones. After the procedure, no significant pain or discomfort is expected.
