Radiologists in emergency department settings are uniquely positioned to identify and provide effective, appropriate care to vulnerable patient populations. Emergency Imaging of At-Risk Patients fills a void in the literature by illustrating challenges in emergency and trauma imaging of vulnerable patients using a head-to-toe approach. Drawing on the vast clinical experience of emergency and trauma radiologists from the largest academic medical centers across North America, this reference presents basic and advanced emergency imaging concepts, relevant case studies, current controversies and protocols, and subtle imaging findings that help guide clinicians to efficient and accurate diagnoses and treatments.
