A variety of tubes, lines and other devices are often identified on imaging studies. While some of these may be familiar and well understood by many radiologists, others may be new or less familiar, and may limit the ability of the radiologist to confirm appropriate placement or identify erroneous placement needing correction. This paper demonstrates and discusses a number of these devices, and offers numerous images of the devices external to the patient, to provide a better understanding and visualization of their components.

Isolated blunt abdominal trauma (BAT) represents about 5% of annual trauma mortality from blunt trauma. As part of multiple-site injury (polytrauma), BAT contributes another 15% of trauma mortality. 1 Exsanguination accounts for 80 to 90% of acute deaths from abdominal injury. More than 75% of such cases are amenable to surgery, and recent years have seen safe extension of nonoperative, image-guided treatments to most victims of blunt-force trauma. 2-21 Early recognition and treatment decisions have been greatly impacted by increasingly sophisticated cross-sectional imaging and image-guided, minimally invasive therapies. 22-32
