Professional medical service of MRI of the Breast
What is it?
MRI (Magnetic Resonance Imaging) is a noninvasive medical test that uses a strong magnetic field, radio frequency pulses, and a computer to create detailed images of organs, tissues, bones, and other internal structures. It does not involve ionizing radiation (x-rays), making it a safe option for many diagnostic purposes.
Why is it Performed?
Breast MRI is not a substitute for mammography or ultrasound but serves as a supplementary tool with several important applications, including:
- Screening for high-risk patients: Women with a high risk of breast cancer.
- Assessing cancer extent: After a breast cancer diagnosis, MRI can determine:
- Tumor size and involvement of underlying muscles.
- Additional cancers in the same or opposite breast.
- Presence of abnormally large lymph nodes in the armpit, indicating possible spread.
- Evaluating abnormalities: Further examining abnormalities that are hard to assess on mammograms.
- Scarring vs. recurrence: Differentiating between post-lumpectomy scarring and recurrent cancer.
- Monitoring chemotherapy: Assessing the effectiveness of preoperative (neo-adjuvant) chemotherapy.
- Breast implants: The most accurate method to detect silicone implant ruptures.
- Guiding biopsy decisions: Used when mammography and ultrasound cannot definitively classify a lesion.
