This issue of the Radiologic Clinics of North America covers most of the major developments in breast imaging that have taken place in the three
years since the last (sixth) breast imaging issue was published in September 2004. Some of the topics are similar but contain substantially updated material; new topics reflect other recent advances in knowledge or technology. The aim of each article is to provide clinically relevant summaries of the state of the art to radiologists both in training and
in practice.
