Overview

Breast MRI provides high sensitivity for cancer detection and extent assessment. It is used for high risk screening problem solving and preoperative planning. MRI complements mammography and ultrasound in comprehensive care.

Indications

Indications include high risk screening evaluation of extent of disease and implant assessment. MRI is used when other modalities are inconclusive or in dense breasts. Contrast enhanced protocols improve lesion detection.

Technique and Interpretation

Dynamic contrast enhanced sequences and kinetic analysis aid characterization. Background parenchymal enhancement affects sensitivity and specificity. Standardized reporting supports clinical decisions.

Limitations and Access

MRI is resource intensive and may have limited availability. False positives and cost are considerations in screening use. Shared decision making guides appropriate utilization.
