Breast MRI
Each exam produces hundreds of images of the breast, cross-sectional in all three directions (side-to-side, top-to-bottom, front-to-back), which are then read by a Radiologist. No radioactivity is involved, and the technique is believed to have no health hazards in general. The hope is that such non-invasive studies will contribute to our progress in learning how to predict the behavior of tumors, and in selecting proper treatments. Breast MRI is an evolving technology and should not replace standard screening and diagnostic procedures (clinical and self exams, mammogram, fine needle aspiration or biopsy).
What should I expect during the exam?The exam typically takes 30 to 45 minutes. First, patients must change into a hospital gown. Then, an IV is inserted into the arm. The patient will lie face down on a table, where the breasts are positioned into cup-like indentations on the table (breast coil). The table is then moved into the MRI machine. The patient will need to lie very still as images are taken. About halfway through the exam, you will receive a painless injection and then more images are taken. If you are claustrophobic or anxious about your MRI exam, don't worry. We can provide you with medication that will make you very comfortable during the exam. However, you will need someone to drive you home. After the exam is complete, the images will be analyzed and interpreted by our Radiologists. Your results will not be available immediately following the exam. Your physician will be contacted with the results. Please let us know if you are taking any hormones. The breast MRI should be scheduled between day 5 and 15 of your menstruation cycle. What is the difference between breast MRI and Mammography?A mammogram is typically used as a first test for breast abnormalities. If a mammogram detects a problem, further specialized mammography and/or ultrasound may be used. If your doctor is still concerned, a Breast MRI is a diagnostic tool that may be considered. Breast MRI has been proven to potentially have value when other tests are inconclusive.
Do I still need to have a Mammogram if I have a breast MRI?Absolutely. A Breast MRI should never take the place of your annual x-ray mammogram. Even if you have a normal Breast MRI, you should still continue to have an annual mammogram, one of the most effective tools in breast cancer detection. What if I'm Pregnant?The decision to scan during pregnancy should be made on an individual basis. There is no known adverse effect of MRI on the fetus. The safety of gadolinium contrast has not been established for pregnant or nursing mothers. However, it is known that gadolinium-based MR contrast media crosses the human placenta and into the fetus when given in clinical dose ranges. Current data indicates that very little gadolinium is secreted in breast milk, with no known toxic effects on the infant. The supervising physician should take this into account, weighing potential risks and benefits, when counseling pregnant and lactating women referred for breast MRI. Current Indications for Breast MRI:Lesion characterization - Breast MRI may be indicated when other imaging examinations, such as ultrasound, mammography and physical examination are inconclusive for the presence of breast cancer.
