Review Meta Analysis
Is functional MR imaging assessment of hemispheric language dominance as good as the Wada test?: a meta-analysis.
To perform a systematic review and meta-analysis to quantitatively assess functional magnetic resonance (MR) imaging lateralization of language function in comparison with the Wada test. ⋯ Functional MR imaging provides an excellent, noninvasive alternative for language lateralization and should be considered for the initial preoperative assessment of hemispheric language dominance. Further research may help determine which functional MR methods are most accurate for specific patient populations.

To systematically examine whether abandoning daily routine chest radiography would adversely affect outcomes, such as mortality and length of stay (LOS), and identify a subgroup in which daily routine chest radiography might be beneficial. ⋯ Systematic but unselective daily routine chest radiography can likely be eliminated without increasing adverse outcomes in adult patients in ICUs. Further studies are necessary to identify the specific patient population that would benefit from daily routine chest radiographs.

Meta Analysis Comparative Study
US or CT for Diagnosis of Appendicitis in Children and Adults? A Meta-Analysis.
To perform a meta-analysis to evaluate the diagnostic performance of ultrasonography (US) and computed tomography (CT) for the diagnosis of appendicitis in pediatric and adult populations. ⋯ From the diagnostic performance perspective, CT had a significantly higher sensitivity than did US in studies of children and adults; from the safety perspective, however, one should consider the radiation associated with CT, especially in children.

To study whether compliance with methodological standards affected the reported accuracy of screening ultrasonography (US) for trauma. ⋯ Bias-adjusted sensitivity of screening US for trauma is low. Adherence to methodological standards included in appraisal instruments like STARD and QUADAS is crucial to obtain valid estimates of test accuracy.

Meta Analysis
Traumatic aortic injury: diagnosis with contrast-enhanced thoracic CT--five-year experience at a major trauma center.
To review the literature and the authors' experience with admission contrast material-enhanced computed tomography (CT) in patients admitted after blunt trauma. ⋯ The CT finding of mediastinal hemorrhage alone is sensitive for traumatic aortic injury, but the finding of aortic injury is more specific.
