OBJECTIVE The objective of our study was to estimate the effective radiation dose to the female breast during CT pulmonary angiography compared with other routine diagnostic imaging techniques. MATERIALS AND METHODS We retrospectively reviewed the demographic data of patients who underwent CT pulmonary angiography between May 2000 and December 2002, the(More)
OBJECTIVE Computed tomographic angiography (CTA) by 16-channel multidetector scanner is increasingly replacing conventional digital subtraction angiography (DSA) for diagnosing or excluding blunt carotid/vertebral injuries (BCVI).

Recent trends within the US military seek to leverage the rapid pace of commercial-off-the-shelf (COTS) platforms for military use. The US Army in particular has started efforts to define a Common Operating Environment (COE) that establishes standards and architectures allowing for a high degree of modularity and enabling hardware-agnostic software(More)
This study aimed to assess the effect of eliminating routine oral contrast use for abdominopelvic (AP) computed tomography (CT) on emergency department (ED) patient throughput and diagnosis. Retrospective analysis was performed on patients undergoing AP CT during 2-month periods prior to and following oral contrast protocol change in an urban, tertiary care(More)
OBJECTIVE The objective of our study was to evaluate the preparedness of postgraduate year (PGY)-2 residents for independent call responsibilities and the impact of the radiology residency training program on call preparedness using an objective DICOM-based simulation module over a 5-year period. MATERIALS AND METHODS A month-long emergency radiology(More)
The purpose of this study is to describe a system for formally reporting second-opinion interpretations of CT imaging exams accompanying patients transferred emergently to a tertiary care center. Second-opinion interpretations of cross-sectional imaging exams rendered in the emergency department setting over 6 months spanning 22 September 2009 to 22 March(More)
OBJECTIVES Recent research describes failed needle decompression in the anterior position. It has been hypothesized that a lateral approach may be more successful. The aim of this study was to identify the optimal site for needle decompression. METHODS A retrospective study was conducted of emergency department (ED) patients who underwent computed(More)
