Breast Magnetic Resonance Imaging (MRI) – Patient Information
Magnetic Resonance Imaging (MRI) of the breasts is a safe, painless, and non-invasive imaging method that uses a magnetic field and radio waves (it does not use X-rays) to create detailed images of the breast tissue.
Breast MRI may be prescribed in the following cases:
For women at high risk of breast cancer (e.g., family history, genetic mutations such as BRCA1/2)
To determine the size and extent of an already diagnosed cancer
For follow-up after breast cancer treatment
To evaluate breast implants – to detect possible damage or rupture
To clarify uncertain or inconclusive results from other imaging methods (ultrasound, mammography); in cases of occult breast cancer (patients with breast cancer metastases but negative mammography and ultrasound findings)
The procedure takes approximately 30–45 minutes
You will lie on your stomach, with your breasts positioned in a special coil designed for the examination
You must remain completely still during the scan
You will hear noises from the MRI machine – earplugs or headphones are usually provided for your comfort
Yes. To distinguish between benign and malignant conditions, the use of an intravenous contrast agent based on gadolinium is required.
The only exception is when the examination is performed solely to evaluate the integrity of breast implants.
Absolute Contraindications:
Presence of metallic implants in the body that are not MRI-compatible
Presence of pacemakers, implanted defibrillators, or neurostimulators that are not MRI-compatible
Relative Contraindications:
Claustrophobia (the procedure may be performed under sedation if necessary)
Tattoos or permanent makeup – they may contain metallic particles that can cause a burning sensation (rarely)
Patients with kidney failure – due to the use of intravenous contrast material
Pregnancy – especially during the first trimester
Premenopausal women:
The optimal time for MRI is between the 7th and 14th day of the menstrual cycle.
Postmenopausal women:
The examination can be performed at any time.
Yes. For a more accurate interpretation of the results, you should bring any previous imaging studies – mammography, ultrasound, or prior MRI scans, as well as documentation of breast interventions, previous biopsies, and histological results.
Of particular importance is documentation from surgical procedures, including details about the type and extent of the operation, histological tumor type, and postoperative course.
Providing these helps the radiologist to:
Increase the accuracy of the examination
Detect changes over time
Determine whether a finding is new, growing, or stable
Avoid misinterpretations
