title: Imaging Foreign Bodies: Ingested, Aspirated, and Inserted.
abstract: Foreign bodies can gain entrance to the body through several mechanisms, ie, ingestion, aspiration, and purposeful insertion. For each of these common entry mechanisms, this article examines the epidemiology, clinical presentation, anatomic considerations, and key imaging characteristics associated with clinically relevant foreign bodies seen in the emergency department (ED) setting. We detail optimal use of multiple imaging techniques, including radiography, ultrasonography, fluoroscopy, and computed tomography to evaluate foreign bodies and their associated complications. Important imaging and clinical features of foreign bodies that can alter clinical management or may necessitate emergency intervention are discussed.
