Comparative StudyThoraco-abdominal CT examinations for evaluating cause of cardiac arrest and complications of chest compression in resuscitated patients.
The objective of the study is to describe the causes of cardiac arrest and complications of cardiopulmonary resuscitation (CPR) on thoraco-abdominal CT examinations for resuscitated patients in our institution. We evaluated the causes of cardiac arrest on thoraco-abdominal CT scans, which was compared with the final diagnosis (determined by consensus of two emergency physicians based on the clinical, imaging, and laboratory findings). Additionally, we evaluated the complications of CPR on thoraco-abdominal CT scans. ⋯ In particular, CT was critical in diagnosis of many respiratory causes (64 %) and all exsanguinations. The most common complications following CPR were skeletal chest injuries (n=48), followed by lung contusion (n=45). Thoraco-abdominal CT examinations are helpful for the diagnosis of cause of cardiac arrest and complications of CPR.

Computed tomography utilization rates after the placement of a scanner in an emergency department: a single-center experience.
The convenience of a computed tomography (CT) scanner in the emergency department (ED) may impact utilization rates. Our primary aim was to determine the rate of utilization before and after the placement of an ED CT scanner. Secondary aims were to determine the rate of utilization by anatomic region and during a 5-month period when the ED scanner was unavailable. ⋯ Overall CT utilization increased after the placement of a scanner in the ED. Most subtypes of scan increased. Utilization was unchanged during a period of ED scanner unavailability, suggesting that increased utilization may be difficult to reverse.

Validation of a clinical decision rule: chest X-ray in patients with chest pain and possible acute coronary syndrome.
Current literature suggests that a large proportion of chest X-rays (CXRs) performed in emergency department (ED) patients with chest pain and suspected acute coronary syndrome (ACS) are unnecessary. The Canadian ACS Guidelines aim to guide clinicians in the appropriate use of CXR within this patient population. This study determined the prevalence of clinically significant CXR abnormalities and assessed the utility of the guidelines in a population of ED patients with chest pain and suspected ACS. ⋯ Had the ACS guidelines been applied to our patient population, the number of CXR performed would have been reduced by 47 %. This study suggests that the ACS Guidelines has the potential to reduce the numbers of unnecessary CXR performed in ED patients. However, this would come at the expense of missing a minority of significant CXR abnormalities.

Minimal aortic injury of the thoracic aorta: imaging appearances and outcome.
The aim of this study is to describe the frequency, computed tomographic angiography (CTA) imaging appearance, management, and outcome of patients who present with minimal thoracic aortic injury. This retrospective study was Institutional Review Board-approved. Eighty-one patients with blunt traumatic aortic injuries (BTAI) were identified between 2004 and 2008, comprising 23 patients with minimal aortic injury (MAI) (mean age, 43.2 years ±18.2 years; 12 males and 11 females) and 58 patients with non-minimal aortic injury (mean age, 42.6 years ±22.7 years). ⋯ In a mean of 466 days of clinical follow-up, no complications were observed in survivors treated without endovascular repair or operation. Minimal aortic injury is identified by multi-detector row CT in more than a quarter of cases of BTAI and has a low mortality. Conservative management is associated with an excellent outcome.
