Abstract
BackgroundFor the evaluation of severely injured trauma patients a variety of total body computed tomography (CT) scanning protocols exist. Frequently multiple pass protocols are used. A split bolus contrast protocol can reduce the number of passes through the body, and thereby radiation exposure, in this relatively young and vitally threatened population.PurposeTo evaluate three protocols for single pass total body scanning in 64-slice multidetector CT (MDCT) on optimal image quality.Material and MethodsThree total body CT protocols were prospectively evaluated in three series of 10 consecutive trauma patients. In Group A unenhanced brain and cervical spine CT was followed by chest–abdomen–pelvis CT in portovenous phase after repositioning of the arms. Group B underwent brain CT followed without arm repositioning by a one-volume contrast CT from skull base to the pubic symphysis. Group C was identical to Group A, but the torso was scanned with a split bolus technique. Three radiologists independently eva...

Aim To evaluate a revised protocol for whole-body computed tomography (CT) for multi-trauma patients in an emergency department and compare it to conventional protocols. Materials and methods Forty-two of 82 multi-trauma patients underwent unenhanced CT examinations of the head, cervical spine, and upper abdomen, followed by an arterial-phase contrast-enhanced CT examination of the thorax and a porto-venous scan of the abdomen and pelvis (conventional protocol). The other 40 patients underwent u...

The use of arterial phase imaging increases CT sensitivity for intrasplenic pseudoaneurysms after blunt abdominal trauma but must be combined with standard portal venous phase imaging for optimal diagnosis and characterization of both active bleeding and splenic parenchymal injury; these two phases together provide optimal diagnostic performance for evaluation of splenic injury.

Background: Contrast-enhanced whole-body computed tomography (also called “pan-scanning”) is considered to be a conclusive diagnostic tool for major trauma. We sought to determine the accuracy of this method, focusing on the reliability of negative results. Methods: Between July 2006 and December 2008, a total of 982 patients with suspected severe injuries underwent single-pass pan-scanning at a metropolitan trauma centre. The findings of the scan were independently evaluated by two reviewers wh...

Background: Computed tomography (CT) of injured patients in the radiology department requires potentially dangerous and time-consuming patient transports and transfers. It was hypothesized that CT in the trauma room would improve patient outcome and workflow. Methods: A randomized trial compared the effect of locating a CT scanner in the trauma room versus the radiology department in two Dutch trauma hospitals. Injured patients aged at least 16 years were assigned randomly to one of these hospit...

Introduction: The Amsterdam Trauma Workflow (ATW) concept includes a sliding gantry CT scanner serving two mirrored (trauma) rooms. In this study, several predefined scenarios with a varying number of CT scanners and CT locations are analyzed to identify the best performing patient flow management strategy from an institutional perspective on process quality. Materials and methods: A total of six clinically relevant scenarios with variables that included the number of CT scanners, CT scanner loc...

The purpose of this study is to assess the influence of different arm positioning techniques on thoracic and abdominal image quality and radiation dose of whole-body trauma CT (wbCT). One hundred and fifty polytrauma patients (104 male, mean age 47 ± 19) underwent wbCT with arms elevated above the head (group A, n = 50), alongside the abdomen (group B, n = 50), and on a pillow ventrally to the chest with both arms flexed (group C, n = 50). Two blinded, independent observers measured image noise ...

Background:Multislice whole body computed tomography is regarded as the method of choice for primary investigation of hemodynamically stable patients with multiple injuries. However, a disadvantage of this method is the high level of radiation to which the patient is exposed. Various recommendations

Abstract Choosing the appropriate imaging in children with accidental traumatic spine injuries can be challenging because the recommendations based on scientific evidence at this time differ from those applied in adults. This differentiation is due in part to differences in anatomy and physiology of the developing spine. This publication uses scientific evidence and a panel of pediatric experts to summarize best current imaging practices for children with accidental spine trauma. The American Co...

Pelvic fractures are potentially life-threatening injuries with high mortality rates, mainly due to intractable pelvic arterial bleeding. However, concomitant injuries are frequent and may also be the cause of significant blood loss. As treatment varies depending on location and type of hemorrhage, timely imaging is of critical importance. Contrast-enhanced CT offers fast and detailed information on location and type of bleeding. Angiography with embolization for pelvic fracture hemorrhage, part...

BackgroundSplit-bolus computed tomography (CT) is a recent development in trauma imaging. Instead of multiple scans in different contrast phases after a single contrast bolus, split-bolus protocols consist of one single scan of the thorax and abdomen after two or three contrast injections at different points of time.PurposeTo evaluate and compare image quality and injury findings of a new triple-split-bolus CT (TS-CT) protocol of thorax and abdomen with those of a portal venous phase CT (PV-CT) ...

With the universal acceptance of contrast-enhanced computed tomography (CT) as the imaging modality of first resort in the assessment of blunt abdominal injury, the trauma radiologist must be able to accurately and rapidly identify the range of CT manifestations of the traumatized abdomen. In this article, we lay out the fundamental principles in CT interpretation of blunt trauma to the hepatobiliary system and spleen, including vascular injury, with a focus on technical and interpretive pearls ...
