Understanding Breast MRI Scans: What You Need to Know
Breast MRI (Magnetic Resonance Imaging) is an advanced imaging technique available to detect breast cancer and disorders. An MRI gives very detailed 3D images of the breast tissue that are not available through mammograms or ultrasounds, so the tests are especially helpful for women at high risk or who need more diagnostic clarity.
Whether you’re currently going through routine screening or you need additional tests following an inconclusive mammogram, knowing what a breast MRI is can help alleviate concerns about the process.
What is a Breast MRI?
A breast MRI is a specialist test that creates accurate images of the breast tissue using radio waves and a powerful magnetic field. An MRI doesn’t use radiation, as do X-rays or CT scans, so it can be a safer procedure for frequent testing.
How It Works:
- During each scan, the device takes multiple cross-sectional breast images, which are then combined by a computer to create a 3D picture of the breast. This allows the radiologist to look at the tissue from several angles and locate tiny abnormalities that cannot be detected as easily by other imaging techniques.
In some cases, a dye (gadolinium) is injected into a vein to help the scan produce clearer images. This dye lights up areas with more blood flow – which is a frequent signal of tumour growth.
When is a Breast MRI Recommended?
Mammograms are the gold standard for checking for breast cancer, but an MRI may be recommended in certain instances:
1. High-Risk Patients
- Women with a significant family history of breast cancer.
- People who have mutations in the BRCA1 or BRCA2 genes.
- Patients who have received chest radiation therapy in the past.
2. Diagnostic Clarity
- If a mammogram or ultrasound is inconclusive, an MRI can provide clearer results.
- To determine the size and extent of the cancer before surgery.
3. Monitoring and Follow-Up
- Evaluating the response to chemotherapy or other treatments.
- Cancer recurrence screening for survivors.
What to Expect During the Procedure
Preparation
- You may be asked to avoid wearing metal objects (jewellery, underwire bras).
- Tell your radiologist if you have breast implants, pacemakers, or claustrophobia.
- Fasting for a few hours may be necessary at some clinics prior to scanning.
The Scan Process
- You will lie face down on a table cushioned with padding, and your breasts will fit into cushioned openings.
- The machine will make a loud knocking noise, and you might be given earplugs or headphones.
- The scan, which usually requires 30 to 60 minutes, requires you to remain in one position for clear images.
Comfort and Safety
- The process is painless and non-invasive, though some find the confined space to be uncomfortable.
- It is also possible to administer contrast, and it is a safe procedure for the majority of patients.
Benefits and Limitations
Key Advantages
- Very sensitive in detecting early-stage cancers, particularly in dense breast tissue.
- Delivers high-definition images for improved surgical planning.
Possible Limitations
- May result in false positives and unnecessary biopsies.
- Not a substitute for mammograms — used in combination with those and other tests.
- More expensive than conventional imaging modalities.
