This book presents a comprehensive and modern approach to the imaging of nontraumatic and traumatic emergencies in pregnant patients. Readers will find a careful review of the relevant imaging-related clinical literature, explanation of imaging appropriateness criteria and guidelines, and enlightening discussion of current controversies in the emergency imaging of obstetric patients. The opening chapter discusses general principles of emergency imaging during pregnancy and offers an overview of an evidence-based approach to imaging interpretation. The remainder of the book describes specific applications of ultrasound, MRI, radiography, and MDCT for the imaging of common as well as less common acute brain, spine, thoracic, abdominal, and pelvic conditions during pregnancy. Clear guidance is offered on the unique challenges that may be encountered during such imaging. Emergency Imaging of Pregnant Patients is written by a group of leading North American and European emergency and trauma radiology experts. It will be of value to emergency and general radiologists, to emergency department physicians and related personnel, to obstetricians and gynecologists, to general and trauma surgeons, and to trainees in all of these specialties.
