Preface
I know that as a resident, I retained more useful information when I read short and basic books over and over than when I read longer, more detailed texts once. The intention of this book is to serve as a basic introductory text on pediatric imaging. The book is written in prose, rather than as an outline, and is intended to be readable. The emphasis is on commonly encountered imaging scenarios and pediatric diseases. The topics included reflect questions that I am commonly asked by residents on the pediatric radiology service, important issues that the rotating residents often seem not to know about, and commonly made mistakes. The book is intended to serve as an excellent introduction or review for a resident or medical student who is about to begin a rotation in pediatric radiology or prepare for radiology oral boards. This book may also serve as a review for a general radiologist who wishes to brush up on pediatric radiology. Pediatric residents or pediatricians who want to learn more about pediatric radiology may also benefit from reading this book.

Acknowledgments
I would like to thank Marlena Tyre for help with proofreading; Judy Racadio, MD, for her help with medical editing and proofreading; James Leach, MD, for his help with the advanced neuroimaging section; and Glenn Minnano for his help with the diagrams. The information in this book is a summation of the material that was taught to me by numerous radiologists, and I would like to thank them for their time and efforts. The case material in this book is the result of the hard work of the faculty, technologists, and trainees in the Department of Radiology at Cincinnati Childrens Hospital Medical Center and the referring physicians who care for these patients. I would like to acknowledge their efforts, without which this book would not be possible.

CHAPTER ONE
Special Considerations in Pediatric Imaging
PEDIATRIC RADIOLOGY AS A POTENTIAL CAREER
Most pediatric radiologists are very happy with both their jobs and their career choice. I know that I am. There are a number of attractive aspects about pediatric radiology. First, one of the most important elements of job satisfaction is the quality of the interactions you have with the people with whom you work. In general, the physicians who choose to go into pediatric subspecialties, as well as health care workers who choose to work at pediatric institutions in general, tend to be nice, gentle people. Aggressive, power-hungry people tend not to want to work with children. This makes a huge difference in the quality of daily life. Also, pediatric subspecialists seem to rely on the opinions of pediatric radiologists more than many of their adult subspecialist counterparts. Similarly, pediatric radiology does not seem to have the same number of turf battles that many adult-oriented departments have.
Another unique feature of pediatric radiology is that you get to be a general specialist. Pediatric radiology is a small part of medical imaging overall and in this sense, the pediatric radiologist is very much a subspecialist. Compared to general radiologists who must have a working knowledge of a daunting amount of information, I believe that most pediatric radiologists feel comfortable that they have an adequate command of the knowledge they need in order to provide outstanding care. At the same time, pediatric radiologists are generalists in the sense that many pediatric radiologists deal with all modalities and organ systems. They get the best of both worlds. It is also possible in pediatric radiology to become a sub-subspecialist, such as a pediatric neuroradiologist, pediatric interventional radiologist, pediatric cardiac imager, or pediatric fetal imager.
The most powerful and fulfilling aspect of becoming a pediatric health care provider is probably the satisfaction that comes from working with and for children. Few activities are more rewarding than helping children and their families. There are many other attractive aspects of pediatric care. First, most kids recover from their illnesses, as compared to elderly adults. Most pediatric illnesses are not self-induced. Pediatric diseases are highly varied and interesting. In addition, pediatric conditions are being increasingly recognized as important precursors to adult illnesses that cause significant mortality ratesobesity, osteoporosis, and glucose intolerance. Finally, children and their families are highly appreciative of pediatricians help.
Finally, and importantly, there are plenty of jobs available in pediatric radiology. It is the radiology subspecialty with the greatest work-force shortage. Currently, there are pediatric radiology opportunities in almost any city in North America and there is no sign that this will change in the near future.
