PURPOSE: The frequency of computed tomography (CT) imaging of trauma patients has given rise to an increase in the discovery of incidental findings. The purpose of this study was to evaluate the frequency and documentation of follow-up recommendations of incidental findings during the initial trauma evaluation. Secondarily, trauma patients with and without incidental findings were compared. We hypothesized that there would be a high rate of incidental findings in trauma patients and that these findings would be poorly documented...

PURPOSE: The purpose of this retrospective study was to determine clinical and imaging factors on computed tomography (CT) associated with clinically worrisome pneumatosis intestinalis (PI) that may aid in the decision to provide conservative management or urgent surgical intervention. METHODS: Informed consent was waived in this IRB approved study. Imaging features assessed included the presence, location, and pattern of PI, bowel dilatation, thickening, enhancement, stranding, portal venous (PV) and mesenteric venous gas, mesenteric edema, free air, and ascites...

PURPOSE: This study examined the value of including a venous phase in addition to the initial arterial phase in the CT angiography evaluation of extremity trauma. METHODS: CT studies from 157 patients (average age 38 years, age range 18-89 years, male 83%, female 17%) were obtained for trauma to the upper or lower extremity with both arterial and venous phases and retrospectively reviewed. The detection rate and type of vascular injury were evaluated by using the arterial phase alone and compared to the detection rate when interpreting the arterial and venous phases together...

PURPOSE: Plain radiographic evaluation of acute shoulder trauma in adults requires a minimum of two projections, commonly the anteroposterior (AP) and lateral scapular projections, with additional projections taken for diagnosis. The aim of this retrospective study was to determine whether the addition of the apical oblique (AO) projection to the AP and lateral scapular projections increases the number and/or alters the types of abnormalities detected in the examination of acute shoulder trauma...

PURPOSE: Conventional radiography is frequently performed in pediatric patients in whom fractures and dislocations are suspected. However, until now, the rate of positive findings of the most commonly performed radiographic examinations in pediatric patients is unknown. The aim of this study was to evaluate the number of positive findings in the 20 most frequently requested standard radiographic examinations in pediatric patients in a level 1 trauma center systematically. METHODS: A transversal cohort study was conducted at a level 1 trauma center in Germany (2008-2014)...

PURPOSE: The purpose of this study was to assess the ability of d-dimer testing to obviate the need for cross-sectional imaging for patients at "non-high risk" for pulmonary embolism (PE). METHODS: This is a retrospective study of emergency department patients at an academic medical center who underwent cross-sectional imaging (MRA or CTA) to evaluate for PE from 2008 to 2013. The primary outcome was the NPV of d-dimer testing when used in conjunction with clinical decision instruments (CDIs = Wells', Revised Geneva, and Simplified Revised Geneva Scores)...

REVIEW
Mona T Vakil, Ajay K Singh
Gunshot injuries are the most common cause of penetrating brain injury (PBI) and carry a high morbidity and mortality. The incidence of PBI has increased over the last decade with an estimated 35,000 civilian deaths annually. Patients that survive to reach the hospital require rapid triage and imaging evaluation. CT findings in conjunction with the Glasgow Coma Scale are typically used to determine which patients are surgical candidates. Radiologists should be familiar with the various injury patterns and imaging findings which are poor prognostic indicators, notably brainstem, bilateral hemispheric, multilobar, or transventricular injuries...

PURPOSE: The purpose of this study is to assess the utility of computed tomography (CT) in predicting clinical outcomes in renal trauma. MATERIALS/METHODS: This retrospective study was IRB approved and HIPAA compliant; informed consent was waived. One-hundred-sixty-two, trauma-related renal injuries (157 adults) from January 01, 2006 to December 31, 2013 were included in this retrospective study. CT findings of vascular and collecting system (CS) injuries were recorded, and American Association for the Surgery of Trauma (AAST) renal injury grades were assigned...

Shock thyroid is a part of the hypovolemic shock complex, which is a constellation of secondary computed tomographic (CT) findings that are observed in patients with hypovolemic shock. However, to the best of our knowledge, there has only been a single report on this condition, which described three cases associated with significant thoracoabdominal trauma. Here, we report four patients with profound hypotension who exhibited similar CT findings as those described in the initial report on shock thyroid, but with a more diverse clinical spectrum...

PURPOSE: The purpose of the study is to determine the incidence of sacral fracture patterns on CT imaging of pelvic trauma patients with correlation with mechanism of injury and pelvic ring injury pattern using the Young-Burgess classification system. MATERIALS AND METHODS: This is a retrospective review of all pelvic CTs with pelvic fractures performed at our level 1 trauma center during a 4-year period from July 2010 to June 2014. RESULTS: Sacral fractures were very common in pelvic trauma patients, being present in 60% of patients presenting to our institution with pelvic fractures...

PURPOSE: The purpose of our study was to assess trends in the imaging of suspected appendicitis in adult patients in emergency departments of academic centers in Canada. METHODS: A questionnaire was sent to all 17 academic centers in Canada to be completed by a radiologist who works in emergency radiology. The questionnaires were sent and collected over a period of 4 months from October 2015 to February 2016. RESULTS: Sixteen centers (94%) responded to the questionnaire...

Razia Rehmani, Angela Han, Jawaad Hassan, Jeffrey Farkas
PURPOSE: Our objective is to identify the effect of prothrombin complex concentrate (PCC) in acute intracranial hemorrhage (ICH) by evaluating intraparenchymal hematoma expansion between initial and follow-up head CT at 5-24 h, in those with positive CTA spot sign (CTASS). CTASS is an independent predictor of hematoma growth (1). Acute ICH, regardless of etiology, can present with quick mental status decline often resulting in irreversible brain damage. Hematoma expansion appears to be a modifiable predictor of clinical outcome and an appropriate target for medical therapy...

PURPOSE: The study aimed to evaluate the image quality in terms of signal-to-noise ratio (SNR) and dose to the lens of the eye and the other nearby organs from the CT brain scan using an automatic tube current modulation (ATCM) system with or without CT gantry tilt is needed. METHODS: An anthropomorphic phantom was scanned with different settings including use of different ATCM, fixed tube current time product (mAs) settings and degree angles of gantry tilt. Gafchromic film XR-QA2 was used to measure absorbed dose of the organs...

PURPOSE: The purpose of this study is to assess the performance of CT angiography (CTA) in the evaluation of penetrating vascular trauma to the extremities in a large cohort of patients at our level I trauma center. METHODS: A retrospective, IRB-approved review of consecutive CTAs for the evaluation of penetrating trauma to the extremities in 446 patients (M/F = 396:50, mean age = 27 years) from 1/1/2005 to 5/1/2015 was performed. Medical records were reviewed to correlate diagnostic imaging findings with clinical history and subsequent interventions...

OBJECTIVE: The objective of our study was to assess the diagnostic quality of low-dose computed tomography (CT) when compared to ultrasound (US) in diagnosis of urolithiasis using STONE score as a predictor of pre-test probability and the Bayesian statistical model to calculate post-test probabilities (POST) for both diagnostic tests. METHODS: STONE score was used to form risk groups to obtain pre-test probabilities. Likelihood ratios (LR) were calculated from external data for low-dose CT and US...

A 69-year-old woman was taken to our emergency department after having been found unconscious. An intraosseous catheter was placed in the head of the right humerus due to inaccessible peripheral veins. With the suspected diagnosis of shock, pulmonary embolism, and mesenteric ischemia, a CT scan of the chest and abdomen was initiated. Pulmonary embolism and mesenteric arterial embolism could be ruled out at excellent image quality.
