MRI can also be used in women with breast implants, prior lumpectomy, or prior radiation, who have decreased sensitivity with mammography. Which imaging modality is used in these cases?

• A. MRI
• B. Mammography
• C. PET-CT
• D. Ultrasound

Answer: (A)

When mammography is less reliable due to implants, prior lumpectomy, or prior radiation, MRI is used because it provides superior soft-tissue contrast and functional information from contrast-enhanced imaging. This makes it more sensitive for identifying cancers that implants or scar tissue can hide on mammography and helps assess the extent of disease around implants or after lumpectomy/radiation. Ultrasound can assist in evaluation but is more operator-dependent and less comprehensive for detecting additional or nonpalpable lesions. PET-CT isn’t the first-line tool for local breast assessment, especially in the setting of implants or post-surgical changes. So MRI offers the most reliable problem-solving capability in these scenarios.
