ReviewHighlights from the scientific and educational abstracts presented at the ASER 2014 Annual Scientific Meeting and Postgraduate Course.
The American Society of Emergency Radiology (ASER) 2014 Annual Scientific Meeting and Postgraduate Course offered dedicated learning sessions, oral presentations, and digital exhibits on a broad spectrum of topics in emergency radiology, including traumatic and nontraumatic emergencies, quality, communication, education, and technology. This article highlights the scientific and educational abstracts presented at the meeting (Emerg Radiol 21:431-471, 2014).

Case ReportsBWH emergency radiology--surgical correlation: sigmoid volvulus.
We describe the radiological and intraoperative correlation of large bowel obstruction due to sigmoid volvulus in a 52-year-old female. The purpose of this article is to emphasize the importance of recognizing sigmoid volvulus as a cause of bowel obstruction in patients presenting with abdominal pain, since it can lead to bowel ischemia and necrosis.

Wrist fractures: sensitivity of radiography, prevalence, and patterns in MDCT.
The aims of this study are to evaluate diagnostic performance of conventional radiographs for wrist fractures using multidetector computerized tomography (MDCT) as a reference standard, to determine prevalence, demographic risk factors including age and sex, and associations among various wrist fractures. A retrospective study was performed, finding a total 455 patients (457 wrists) who had wrist trauma and who had undergone a radiography and subsequent MDCT examination during a 45-month period. The MDCT and radiographs of the patients were reviewed by two radiologists, and a consensus was obtained for the presence of fracture. ⋯ The sensitivities of radiography ranged 0-41.2 % for other carpal bone except scaphoid (66 %) fractures and 66.7-80 % for the proximal metacarpus, distal ulna, and radius fractures. Wrist fractures appear to be overlooked on radiography. Further imaging should be warranted for patients who are clinically suspicious for wrist fracture in emergency rooms.

The prevalence of pulmonary embolism among patients suffering from acute exacerbations of chronic obstructive pulmonary disease.
The clinical diagnosis of acute pulmonary embolism (PE) in patients with acute exacerbation of chronic obstructive pulmonary disease (COPD) is often difficult due to the similarity in the presenting symptoms of the two conditions. The purpose of this study was to determine the prevalence of PE in patients with acute exacerbation of COPD. Forty-nine consecutive patients admitted to our medical center for acute exacerbation of COPD were investigated for PE (whether or not clinically suspected), following a standardized algorithm based on D-dimer testing and computed tomography pulmonary angiography (CTPA). ⋯ Presenting symptoms and signs were similar between patients who did and did not have PE. PE was detected in 18 % of COPD patients who were hospitalized for an acute exacerbation. This finding supports the systematic evaluation of PE in hospitalized COPD exacerbated patients.

Diabetic striatopathy is a rare and life-threatening manifestation of diabetes mellitus. The disease commonly affects individuals of Asian descent, females, and the elderly. Patients usually present with hemiballism-hemichorea caused by nonketotic hyperglycemia. ⋯ Laboratory tests reveal raised blood glucose and hemoglobin A1C levels which indicate poorly controlled diabetes. Neuroimaging provides suggestive findings of diabetic striatopathy which are hyperattenuation on computed tomography and hyperintensity on T1-weighted magnetic resonance imaging in the basal ganglia. In this case report, our aim is to present neuroimaging findings in an adult man with sudden onset of hemiballism associated with nonketotic hyperglycemia.
