Emergency Radiology: Case Studies
Working in the Emergency Department is a wonder. There is an extraordinary range of clinical problems to solve and opportunities to attend to patients in need. Diagnostic imaging plays an important role in many clinical situations, although its role must always remain secondary to a carefully performed history and physical examination.
Many different imaging modalities are employed in emergency practice including conventional radiography, CT, ultrasonography and, less often, MRI, nuclear scintigraphy, angiography, and enteric contrast radiography. Nonetheless, conventional radiography remains the most frequently used modality and the one that emergency clinicians are most frequently called upon to interpret. In addition, an understanding of radiographic findings is important to deriving essential information from the radiologist’s report and to communicating accurately with medical and surgical colleagues. Conventional radiography is therefore the focus of most of the cases in this book. Noncontrast head CT, which is the chief imaging study for various neurological emergencies, is covered in one section. Other imaging modalities are discussed where they play a role.
This book is based on clinical cases, and is designed to hone the reader’s skills in the use and interpretation of radiographs. Easily missed disorders and diagnostic dilemmas are emphasized. Although not exhaustive, the book encompasses many of the major areas in which radiography is helpful in achieving a diagnosis. By limiting the range of topics, these areas can be discussed in greater depth than is possible in an all-inclusive textbook.
The book is divided into seven sections: chest, abdomen, upper and lower extremity, cervical spine, head CT and face. Each section begins with an introductory chapter that discusses the radiographic principles for that region. These include indications for radiography, radiographic views, anatomy, and principles of interpretation.
