MRI uses a powerful magnetic field, radio waves and a computer to produce detailed pictures of the structures within the breast. This is used to detect breast cancer and other abnormalities in the breast.
MRI breast does not replace mammography or ultrasound imaging. It is not required in all women diagnosed with breast cancer. It is a supplemental tool / problem-solving tool. It is used
To determine the extent of cancer in a newly diagnosed patient: To know the size of cancer and the structures that are involved. If there are other cancers in the same breast or unsuspected cancer in the other breast. It is also helpful to evaluate if any enlarged glands are present in the armpit.
To Screen for breast Cancer in High-risk women: A Screening MRI is recommended along with a yearly mammogram.
Further evaluation of abnormalities on mammography: That is in a difficult position to assess further or in a difficult position to biopsy. MRI can be used to determine if the abnormality needs a biopsy or can be safely be left alone.
Evaluating the lumpectomy site following breast cancer treatment: Scarring and recurrent cancer can look identical on mammography and ultrasound. If any change at the lumpectomy site on mammogram or physical examination is concerning, MRI can help to differentiate between the scar and cancer recurrence.
To evaluate the tumour response to chemotherapy: Sometimes breast cancer is treated with chemotherapy before surgery. This is called Neoadjuvant chemotherapy. In these patients, MRI is used to monitor how well the chemo is working and to assess the amount of tumour still present prior to surgery.
Evaluating breast implants: MRI is the test of choice to assess implant integrity.
Unless you are told otherwise, take your medicines and light food as usual.
Schedule MRI at the beginning of your menstrual cycle: In premenopausal women, contrast MRI for screening is preferably performed during the 2nd week of the menstrual cycle (7-14days). This is to avoid potential false-positive results. For diagnostic purpose, this is not applied and MRI scheduling should not substantially delay therapy planning. Looking for MRI scan in Bangalore?

Get a Kidney function test done: All most all breast MRI examinations require an injection of contrast material, called gadolinium. The chances of an allergic reaction to gadolinium is very minimal, however, a normal kidney function is a prerequisite prior to the administration of the contrast. A blood test to check kidney function is required for a contrast study. Inform the technologist if you have any health problems or had any surgeries.
Tell the doctor if you are pregnant: Women should inform if there is a chance they could be pregnant. To date, there is no information indicating that MRI is harmful to an unborn child. However, MRI is generally not done in 1st trimester as the baby will be exposed to a strong magnetic field. Pregnant women should not receive gadolinium contrast unless absolutely necessary.
Tell the doctor if you are nursing a baby: Because only a very small percentage of gadolinium is excreted into the breast milk and absorbed by infants gut, it is concluded from available data that, it is safe to continue breastfeeding after a contrast study (ACR Committee on Drugs and Contrast Media, 2020). However, if you are concerned, stop breastfeeding for 12-24hrs after MRI during which time, the body will eliminate the dye.
Antianxiety medication: If the patient is claustrophobic or anxious, they may consider taking mild sedative from their doctor prior to examination.
Don’t wear anything metallic during the MRI: Patient is required to change into hospital gown and bra should be removed. Any metal objects like hair clips, jewellery, dental work and body piercings to be removed. Metal and electronic items interfere with the magnetic field. They can cause burns or become harmful projectiles in the scanning room.
Inform the technician about any previous surgeries and metal implants or electronic devices in the body: MRI is safe in the majority of the times. However, people with some implants such as the defibrillator, pacemaker, cochlear implant etc should not enter MRI scanning without being evaluated first.
