Breast MRI has some indications and does not use regularly. Breast MRI is not the primary modality for diagnosis of breast lumps and does not provide any additional findings to ultrasound and mammographic results and has both false-positive and false-negetive results.

Indications of breast MRI:

• Restricted mammographic findings due to breast augmentation resulting from silicon, saline implants, and silicone injection.
• Determination of breast cancer invasion to pectoralis major, serratus anterior, and intercostal muscles.
• Further evaluation for breast lumps beside examination, mammographic, and ultrasonographic findings.
• Evaluation of contralateral breast in patients with breast carcinoma.
• Screening method for asymptomatic and high risk patients.
• Determining patient’s response to neoadjuvant chemotherapy in comparison to previous, during, and after imaging findings.
• Determining residual disease after lumpectomy in individuals with positive margin.

Breast MRI is not the primary imaging modality for the diagnosis of breast lumps and does not provide any additional findings to ultrasound and mammographic results. Also false-positive findings of breast MRI may lead to unnecessary biopsies. False-negative findings of breast MRI are present and require follow-up evaluation regarding ultrasound and mammographic features.^[3]
