Chest radiographs are one of the most complex imaging modalities to interpret. The objective of this study was to assess how accurately emergency physicians interpreted chest radiographs in relation to radiologist reports. Radiological descriptions of chest radiographs from 667 emergency department (ED) patients, aged 14 to 84 years, were retrospectively reviewed. ⋯ Emergency department physicians frequently missed specific radiographic abnormalities, and there was considerable discrepancy between their interpretations and those of trained radiologists. The agreement for some diagnostic categories such as pneumonia and congestive heart failure was low. This study's findings emphasize the need for improving interpretive skills among ED physicians.

Case ReportsCases from the Cleveland Clinic: cerebral venous sinus thrombosis presenting to the emergency department with worst headache of life.
A 31 year old woman presented with the worst headache of her life and was diagnosed with cerebral venous sinus thrombosis (CVST) by routine unenhanced computed tomography (CT) scan, subsequently confirmed with magnetic resonance imaging (MRI) and magnetic resonance venography (MRV). Awareness of this less common cause for acute neurological presentation in the Emergency setting is important; the imaging characteristics of CVST are reviewed.

Case ReportsHypopharyngeal perforation because of blunt neck trauma.
Hypopharyngeal rupture because of blunt neck trauma is an extremely rare clinical entity. Early diagnosis and appropriate management are of great importance, given that an overlooked injury can lead to catastrophic consequences. We herein describe the case of a 21-year-old man who presented with a knee injury after a low-speed motor cycle accident, but was otherwise asymptomatic. ⋯ Complete imaging examinations finally revealed characteristic findings of hypopharyngeal perforation. The patient was treated conservatively with success. A high degree of clinical suspicion is therefore the key to an early diagnosis and successful management of this rare injury.

Comparative StudyDetection and evaluation of intracranial aneurysms with 16-row multislice CT angiography: comparison with conventional angiography.
The aim of our study was to compare multidetector row computed tomography (CT) angiography (MDCTA) with digital subtraction angiography (DSA) in the detection and characterization of intracranial aneurysms. Between September 2005 and May 2007, 55 consecutive patients with suspected intracranial aneurysms underwent conventional DSA and MDCTA. Thirty-two women and 23 men were enrolled in the study. ⋯ Regarding the aneurysms smaller than 3 mm, for readers 1 and 2, the sensitivities were 84.6% (95% CI = 57.8-95.7%; 11 of 13) and 92.3% (95% CI = 66.7-98.6; 12 of 13), respectively. MDCTA is accurate in the detection and characterization of intracranial aneurysms and can be used as a reliable alternative imaging technique to DSA. A strategy of using CT angiography as the primary method, with DSA reserved for any cases of uncertainty, appears safe and reliable.

Case ReportsSystemic air embolism after percutaneous transthorasic needle biopsy of the lung.
Computed tomography (CT)-guided percutaneous transthoracic biopsy of the lung is a well-established diagnostic technique, but it can pose complications to the patients. Air embolism is one of the rarest but potentially fatal complications of this procedure. ⋯ Careful reviewing of the obtained CT images during the procedure may avoid a missing systemic air embolism and can immediately provide an adequate therapy also in asymptomatic patients. This extremely rare complication is an inevitable event and may happen in spite of appropriate experience and meticulous care.
