M r. E. Stephen .Am.is. coauthor of the second through fourth
editions, decided that his busy schedule would not allow
him to participate in the preparation of the fifth edition of
TtXtflook ofUroradiology. We therefore asked Dr. Richard H. Cohan,
Professor of Radiology at the University of Michigan and Dr. Stuart
G. Silverman, Professor of Radiology at Harnlrd Medical School, to
participate on a limited basis in the preparation of this new edition
to fill some of the void that resulted from Steve's decision.
The original Textbook of Uroradiology grew out of discussions between the then Williams & Walkins publishing house
and Dr. Ronald McCallum, a uroradiologist at St. Michael's
Hospital in Toronto and Professor of Radiology at the University
of Toronto. Dr. McCallum invited Drs. Dunnkk and Sandler
to join him in this effort; the result of which was the first edition of this book, originally published in 1990. As stated in the
Preface of that edition, our goal was to produce an introductory textbook of uroradiology aimed at both radiology residents
and practicing radiologist& that included oDly material that we
felt the reader ought to know, not all there is to know about a
particular topic. When Dr. McCallum retired, Drs. Dunnick
and Sandler were joined by Drs. Newhouse and Amis who had
published their own introductory tatbook, called Essentials of
Uroradiology. These same four authors produced the third edition, published in 2001 and the fourth edition in 2008.
With each edition, the authors struggled to identify material
that should be included and deleted to keep the book a manageable
size. Material concerning excretory urography has been further
reduced to reflea: its waning importance to the practice of uroradiology. However, the images and interpretative skills needed for
excretory urography can be applied directly to cr urography. and
some traditional material has been retained.
In order to keep the material as &esh as pos.sible, the authors
decided to rotate the authorship of several of the individual chapters among themselves, although, in keeping with the tradition
of Textbook of Uroradiology, individual authorship of the separate chapter$ has not been designated to reflect our view that the
book is a collaborative effort. We have once again used "Suggested
Readings• at the end of each chapter should the reader decide to
gather additional information about a particular topic, but no individual references were deemed necessary.
We continue to a:pea: that the reader will find Textbook of
Uroradiology a useful addition to his or her horary and hope that
this new version will meet with the same level of acceptance enjoyed by its predecessors.
