Gamuts in radiology

New entries of particular interest in this book include: F-51, the International Labor Organization 1980 international class of radiographs of the pneumoconioses; F-102, breast calcifications; G-13A, portal hypertension; and a whole new section (H-75 to H-84) for pelvic sonography. Since the first edition was published 12 years ago, old diseases have been reclassified and renamed, and new imaging modalities have given a new way to look at these diseases. This shift in diagnostic imaging is reflected throughout the book.
