Guilford Radiology is accredited by the American College of Radiology (ACR) to perform MRI Breast exams.
Magnetic resonance imaging (MRI) is a noninvasive test used to diagnose medical conditions. MRI uses a powerful magnetic field, radio waves and a computer to produce detailed pictures of internal body structures. MRI does not use radiation (x-rays). MRI of the breast offers valuable information about many breast conditions that cannot be obtained by other imaging modalities, such as mammography or ultrasound.
MRI of the breast is not a replacement for mammography or ultrasound imaging but rather a supplemental tool that has many important uses.
Screening in women at high risk for breast cancer - For women at high risk for breast cancer, typically because of a strong family history, MRI may be an appropriate tool to screen for breast cancer. A strong family history is usually a mother or sister who has had breast cancer before age 50. It can also be aunts or cousins, including those on your father's side. Relatives who have had ovarian cancer also increase your risk. Your radiologist or primary care doctor can look at your family history and determine if screening MRI may be appropriate for you. Depending on your family history, genetic counseling may also be recommended.
Determining the extent of cancer after a new diagnosis of breast cancer - After being diagnosed with breast cancer, a breast MRI may be performed to determine how large the cancer is and whether it involves the underlying muscle, if there are other cancers in the same breast and whether there is an unsuspected cancer in the opposite breast, if there are any abnormally large lymph nodes in the armpit, which can be a sign the cancer has spread to that site.
Further evaluating hard-to-assess abnormalities seen on mammography - Sometimes an abnormality seen on a mammogram cannot be adequately evaluated by additional mammography and ultrasound alone. In these rare cases, MRI can be used to definitively determine if the abnormality needs biopsy or can safely be left alone.
Evaluating lumpectomy sites in the years following breast cancer treatment - Scarring and recurrent cancer can look identical on mammography and ultrasound. If a change in a lumpectomy scar is detected by either mammography or a physical exam, MRI can help determine whether the change is normal maturation of the scar or a recurrence of the cancer.
Following chemotherapy treatment in patients receiving neoadjuvant chemotherapy - In some cases, breast cancer will be treated with chemotherapy before it has been removed by surgery. This is called neoadjuvant chemotherapy. In these cases, MRI is often used to monitor how well the chemotherapy is working and to reevaluate the amount of tumor still present before the surgery is performed.
Evaluating integrity of breast implants - MRI is the best test for determining whether silicone implants have ruptured.
MRI exams may be done on an outpatient basis. You will be positioned on the MRI exam table. For an MRI of the breast, you will lie face down on a platform specially designed for the procedure. The platform has openings to accommodate your breasts and allow them to be imaged without compression. The electronics needed to capture the MRI image are actually built into the platform.
It is important to remain very still throughout the exam. This is best accomplished by making sure you are comfortable and can relax rather than trying to actively hold still tensing your muscles. Be sure to let the technologist know if something is uncomfortable, since discomfort increases the chance that you will feel the need to move during the exam.
The imaging session lasts between 30 minutes and one hour.
For the MRI exam, if claustrophobia or anxiety is a problem, your referring physician may wish to prescribe a mild sedative to be given prior to the study. No other pre-visit preparation is necessary. You will need to remove all jewelry, hairclips, pony-tails and bobby pins. In addition, you will need to remove all clothing containing metal. This would include bras with metal enclosures and jeans with metal zippers and buttons. You will be provided a gown and a secure locker in which valuables can be placed.
Our MRI equipment has a weight limit of 440 pounds.
