Breast MRI Vs. Mammogram: Which Is Better for Breast Cancer Detection?

Breast MRI Vs. Mammogram: Which Is Better for Breast Cancer Detection?

Mammograms have been the most commonly used test for breast cancer screening since the late ’70s; however, breast MRI is becoming an increasingly valuable tool for breast cancer detection due to its many benefits. Both devices have advantages and limitations. The best choice for your particular situation depends on several factors.

What Is a Mammogram?

Mammograms use X-ray radiation to penetrate breast tissue and determine differences in tissue density. Breast tumors usually have a higher viscosity than other breast tissue and are visible on an X-ray as a lighter-colored, solid mass. During a mammogram, the breast is compressed to permit the radiation to pass through thinner layers of tissue. Scans are taken of the breast at multiple angles to ensure all parts of the breast are scanned.

What Is a Breast MRI?

Magnetic resonance imagining machines use potent magnets, computers, and radio frequencies to generate precise images of the structures and organs inside the body. Unlike mammograms, an MRI for breast cancer does not use radiation. No compression of the breast tissue is needed for a breast MRI. Patients undergoing a breast MRI are usually given a contrast dye that helps enhance the image resolution, making it easier to differentiate tissue density.

What Are the Advantages of a Mammogram?

Because MRIs enhance images of both benign and cancerous lesions, mammograms are less likely to produce a false-positive result than MRIs. Additionally, mammograms can detect calcification, making it easier to tell the difference between a benign tumor and a malignant one. Mammograms do not require the use of a contrast dye. Mammograms are usually less expensive than MRI scans. Your insurance company may require you to have a mammogram before they authorize a breast MRI.

What Are the Advantages of a Breast MRI?

Because of the higher resolution, breast MRIs can better visualize masses in dense tissue than mammograms. This difference is of particular importance for women who have dense breasts. Many patients find having a breast MRI to be more comfortable and less invasive than a mammogram because the patient can remain dressed for the procedure, and the breast tissue does not need to be compressed. Open MRIs, such as the scans performed by Brooklyn Open MRI, are exceptionally comfortable because the Open MRI machine is available on all sides, reducing the claustrophobia some patients experience when using a traditional MRI machine. Patients who are concerned about radiation exposure may prefer an MRI scan because no radiation is used.

When Should a Breast MRI vs. Mammogram Be Perform?

It is recommended that women at high risk for developing breast cancer consult their doctor about having an MRI test done in conjunction with a mammogram. Several factors may place a patient in the high-risk category:

  • BRCA1 and BRCA2 or other genetic mutations
  • A first-degree relative who has an inheritable breast cancer mutation
  • Breast cancer risk of 20 to 25 percent, based on National Cancer Institute assessment tools
  • Received radiation therapy to the breast between the ages of 10 and 30

Additionally, women who have conditions known to predispose them to breast cancer, such as atypical ductal hyperplasia, may need an MRI. Breast MRIs may also be appropriate for women who have had a mastectomy on one side or have dense breast tissue.
