Role of magnetic resonance imaging in the diagnosis and single-stage surgical resection of XXXX of the breast.

BACKGROUND: Conventional imaging with mammography and ultrasonography has a low sensitivity for diagnosis and a tendency to underestimate the extent of @entity1137 ( @entity1137 ) of the breast. The aim was to determine whether magnetic resonance imaging (MRI) had any advantages for the characterization of @entity1137 . METHODS: Twenty @entity1 with histologically proven @entity1137 underwent preoperative imaging with MRI. MRI was performed to aid detection of @entity5 in six @entity1 with a clinically suspicious presentation but normal or indeterminate imaging on mammography and ultrasonography. In 14 @entity1 MRI was performed to determine @entity5 extent. RESULTS: MRI accurately identified @entity5 in five of six @entity1 with normal or indeterminate conventional imaging. In seven of 14 @entity1 in whom MRI was performed to determine @entity5 extent, it provided significant additional information. These included four @entity1 in whom conventional imaging grossly underestimated @entity5 size, two @entity1 in whom MRI identified an unsuspected @entity0 and one @entity1 in whom MRI predicted @entity5 invasion of the pectoral muscle. The correlation between @entity5 size on histological examination was better with MRI (r = 0.967) than with mammography (r = 0.663) and ultrasonography (r = 0.673). CONCLUSION: MRI can provide considerable additional information in the detection and characterization of @entity1137 .
