Effect of oral contrast for abdominal computed tomography on emergency department length of stayEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract Computed tomography of the abdomen and/or pelvis (CTAP) is frequently used in the emergency department (ED) allowing diagnosis of a variety of conditions, but requiring a prolonged period of preparation. To determine whether not requiring oral contrast for CTAP reduces ED length of stay (LOS). Retrospective cohort of adult patients visiting an academic ED over 13 weeks around a radiology protocol change. Before the change, many CTAPs required oral contrast; thereafter, oral contrast was not required. LOS was compared before and after the change among all adult ED patients. Among patients underg...

Following trauma, should adult wrist radiographic examinations be two or three projections?Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract Literature review and anecdotal evidence appears to suggest a variation in the number of imaging projections used to demonstrate recent injury to the wrist, dependent on which Accident and Emergency (A&E) radiology department a patient attends. Some departments routinely undertake two projections (dorsi-palmar and lateral) whilst others include a dorsi-palmar oblique projection. The aim of this research was to assess if the inclusion of the additional projection altered the sensitivity of bony injury detection. Four readers reported 250 anonymous image sets, initially of two projections, and then at...

Overuse of concomitant foot radiographic series in patients sustaining minor ankle injuriesEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract Radiographic series of the foot are often obtained in conjunction with ankle X-rays when the clinical presentation is limited to trauma to the ankle. The Ottawa Ankle and Foot Rules were established in 1992 and serve as reliable guidelines to determine when an ankle or foot series is warranted in patients who have sustained minor ankle and/or foot injury. We retrospectively reviewed radiographic studies of all patients over a period of 18 months who simultaneously had ankle and foot plain radiographs performed for acute complaints limited to the ankle alone.

Abstract Arterial injuries in the neck may be secondary to blunt or penetrating trauma. Because of clinical difficulties in early identification of these injuries as well as their potentially catastrophic consequences, imaging is indispensible in the diagnosis of arterial injuries in the neck.

Abstract The “whirl sign” is an uncommon finding on emergency CT. However, it is easy to overlook if not kept in mind. Its recognition is of capital importance, being most of its causes potentially lethal. Surgical treatment is also mandatory when signs of complication are found. The whirl sign is usually found associated to midgut, cecal and sigmoid volvulus, small-bowel volvulus and closed-loop obstructions, and post-surgical mesenteric windows (including retroanastomotic hernias). CT is an optimal imaging technique to depict the so-called sign and associated CT features suggesting complication (circum...

Abstract Computed tomography has evolved to become the principal imaging modality in the evaluation of colorectal trauma. Direct signs of colorectal trauma are usually highly specific but relatively insensitive and, therefore, indirect signs are important in the diagnostic of colorectal injuries. In addition, prompt recognition of colorectal injury is crucial as even short delays in its diagnosis have been shown to significantly increase both morbidity and mortality. All these things make colorectal injury a challenge for radiologists. The purpose of this review is to describe and analyze the various compute...

Abstract Computed tomography (CT) has been shown to be increasingly useful in the evaluation of blunt trauma patients with suspected abdominopelvic vascular injuries. CT findings of abdominopelvic vascular insult may be broadly characterized as end-organ abnormalities or direct evidence of vascular injury. End-organ abnormalities implying an underlying vascular insult include identifying an area of relative hypoperfusion in solid organ injury. Direct evidence of a vascular injury includes identifying an irregular or thrombosed vessel or an area of active hemorrhage, among other findings. This review article ...

Extremity CT angiography: application to trauma using 64-MDCTEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract Evolving multi-row detector computed tomography (MDCT) technology has resulted in increasing utility of CT angiography (CTA) in extremity vascular trauma diagnosis and characterization. Given the widespread availability as well as the ease of acquiring CTA in the trauma setting, CTA is increasingly being used as the initial diagnostic evaluation in extremity vascular trauma, replacing digital subtraction angiography in many institutions. One of the significant advantages of the application of 64-MDCT to extremity vascular trauma is the ability to integrate CTA into routine trauma torso protocols. Th...

Correlation of incidental colorectal wall thickening at CT compared to colonoscopyEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
This study focused on those 150 patients and analyzed the correlation between the CT scan findings of wall thickening of the colon and the findings on colonoscopy. The CT scan findings correlated with abnormal colonoscopic findings in 96 out of 150 (64%) of our cases. In a specific subgroup, 12 out of 12 (100%) of these CT scans were also noted to have a mass lesion, as well as colon wall thickening, all of which were consistent with an adenoma or carcinoma found on colonoscopy. Incidental colorectal wall thickening at CT scan is due to nonspecific colitis in majority of the cases. Admission to the hospital should be ...

Findings in multi-detector row CT with portal phase enhancement in patients with mesenteric venous thrombosisEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract There exists no systematic evaluation on the findings in multi-detector row computed tomography (MDCT) with portal phase enhancement in patients with mesenteric venous thrombosis (MVT). Patients with MVT between 2004 and 2006 were identified at Malmö University Hospital, Sweden. Thirty patients had MVT. Median age was 58 years (interquartile range, 46–72), and 57% (17) were men. MDCT with portal phase enhancement showed MVT in 19 out of 20 investigated patients at first evaluation, even though there was clinical suspicion in only one, and conservative management was possible in 19 (95%). Cen...

CT evaluation of placental abruption in pregnant trauma patientsEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract The purpose of the study was to assess the possibility of placental injury detection on computed tomography (CT) in pregnant trauma patients. The images and dictated reports of 44 CT scans of pregnant women who presented to the University of California Irvine Medical Center (UCIMC) from 2003 to 2008 for traumatic abdominal conditions were reviewed for placental abruption. Performances of original dictated reports, an untrained reviewer, and a trained reviewer (who was trained on 22 non-traumatic scans) were compared. Of the 66 pregnant women who received abdominal CT scans, 44 sustained abdominal tr...

Active extravasation of the abdomen and pelvis in trauma using 64MDCTEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The objective of this study was to determine the clinical and management implications of the finding of active extravasation in blunt or penetrating trauma patients evaluated with abdomino-pelvic computed tomography (CT) using 64MDCT technology. This HIPAA compliant, retrospective study was IRB-approved, and the need for consent was waived. All adult patients scanned with 64MDCT who sustained blunt or penetrating abdomino-pelvic trauma and had findings of active extravasation at our Level I trauma center during a 30-month period were included. Two radiologists reviewed all abdomino-pelvic CT scans and characterized the...

Ureteral tear at the ureteropelvic junction: a complication of liposuctionEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
We report the case of a 47-year-old woman who presented to the emergency room with gross hematuria during liposuction of the abdomen. Computed tomography (CT) using hematuria protocol demonstrated extravasation of contrast at the right ureteropelvic junction and a small urinoma in the right perinephric space. The diagnosis of ureteral tear at the ureteropelvic junction (UPJ) was confirmed. A ureteral stent was placed at surgery. Visceral injuries and other complications associated with liposuction have been described. However, this is the first reported case of a ureteral tear related to liposuction. Content Type Jo...

What ER radiologists need to know about radiation risksEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract The annual per capita medical dose in the US is currently 3 mSv, and has increased by about 600% since the early 1980s. Medical doses now account for approximately 50% of the total US population dose, and will likely continue to increase for the foreseeable future. An average patient at a Level 1 trauma center, with an Injury Severity Score of 14, is expected to undergo imaging procedures that will result in an effective dose of approximately 40 mSv. The median age of a trauma patient in the ER setting is about 30 years, and the male cancer incidence from this amount of radiation is e...

Multimodality imaging of hepato-biliary disorders in pregnancy: a pictorial essayEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract Hepato-biliary disorders are rare complications of pregnancy, but they may be severe, with high fetal and maternal morbidity and mortality. Imaging is, therefore, essential in the rapid diagnosis of some of these conditions so that appropriate, life-saving treatment can be administered. This pictorial essay illustrates the multimodality imaging features of pregnancy-induced hepato-biliary disorders, such as acute fatty liver of pregnancy, preeclamsia and eclampsia, and HELLP syndrome, as well as those conditions which occur in pregnancy but are not unique to it, such as viral hepatitis, Budd–Chiar...

A template approach for detecting fractures in adults sustaining low-energy ankle traumaEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract Low-energy trauma such as sprains account for 75% of injuries to the ankle; therefore, ankle pain is one of the most common problems encountered by emergency physicians. A close inspection of the radiographs is often required for diagnosis and this depends on the knowledge of high-risk areas since proper treatment relies on the accuracy of the initial diagnosis. In this article, we will present a template that has helped to increase the accuracy for detecting subtle avulsion fractures, chip fractures, and osteochondral fractures of the hind foot in adults sustaining low-energy ankle injuries. By uti...
