This book provides a comprehensive review of contrast-enhanced magnetic resonance imaging of the breast. Following a short introduction providing relevant background information, the book is divided into three main sections. The first discusses technical requirements and outlines an optimized standard technique, as based on multicenter studies and the authors' own experience. The appearance of benign and malignant breast tissues is then discussed and illustrated, and the value of MRI appraised relative to that of other imaging modalities. The final section provides data on the accuracy of MRI in different contexts and attempts to define its current role. The book concludes by discussing the application of MRI for the diagnosis of implant rupture and likely future developments.
