Which imaging modality is used for screening high-risk patients?

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

Answer: (A)

When screening high-risk patients, the goal is to detect cancers as early as possible, even when they’re small or in dense breast tissue. Magnetic resonance imaging (MRI) provides the highest sensitivity among imaging options for this group, especially for women with BRCA mutations, strong family history, or prior chest radiation. Because MRI uses contrast-enhanced, cross-sectional imaging, it can reveal cancers that mammography might miss, complementing mammography rather than replacing it. While ultrasound can be helpful as a supplemental tool in certain situations, it isn’t used alone as the primary screening modality for high-risk individuals. Thermography lacks validated evidence for screening, and PET-CT is not used for routine screening due to higher cost, radiation exposure, and limited usefulness in detecting early, asymptomatic cancers.
