Breast MRI (Magnetic Resonance Imaging) has become increasingly used in the diagnosis of breast diseases. It utilizes harmless radio waves to create detailed images of the breast and does not involve radiation.
Breast MRI is the most sensitive method for detecting breast cancer. However, due to its longer duration, higher cost, and the fact that some patients may not be able to undergo MRI (due to claustrophobia or physical limitations), it is not routinely used for breast cancer screening. However, it has become a helpful adjunct to mammography for high-risk women (such as those with a first-degree relative who has had breast cancer). It is often used in annual screenings for women at higher risk for breast cancer.
Breast MRI is typically used as a follow-up examination after mammography and breast ultrasound. It helps in the detailed evaluation of suspicious findings from other imaging methods. It is usually considered a “problem-solving” tool when other tests provide inconclusive results.
How is a Breast MRI Performed ?
For a breast MRI, the patient is typically asked to undress from the waist up and lie face down on the MRI table. Special, wide cups designed for the breast are placed into the MRI machine to support the breasts, without the need for compression.
During the MRI, a contrast dye is administered through an intravenous line. This contrast material helps highlight the breast tissue more clearly, allowing for better imaging. The risk of an allergic reaction to MRI contrast agents is very low.
