However, while the knowledge base regarding effective medical therapies continues to improve, the practice of medicine continues to lag behind, and errors are distressingly frequent. Regarding the(More)
PURPOSE To estimate cumulative radiation exposure and lifetime attributable risk (LAR) of radiation-induced cancer from computed tomographic (CT) scanning of adult patients at a tertiary care academic medical center. MATERIALS AND METHODS This HIPAA-compliant study was approved by the institutional review board with waiver of informed consent. The cohort(More)
PURPOSE To determine the effect of evidence-based clinical decision support (CDS) on the use and yield of computed tomographic (CT) pulmonary angiography for acute pulmonary embolism (PE) in the emergency department (ED). MATERIALS AND METHODS Institutional review board approval was obtained for this HIPAA-compliant study, which was performed between(More)
PURPOSE To describe new techniques for percutaneous biopsy with use of an open-configuration magnetic resonance (MR) imaging system with integrated frameless stereotaxic guidance tools. MATERIALS AND METHODS In 28 patients, biopsy was performed in which the image plane was interactively controlled by the position of a hand-held probe attached to the(More)
OBJECTIVE Although computerized physician order entry (CPOE) may decrease errors and improve quality, hospital adoption has been slow. The high costs and limited data on financial benefits of CPOE systems are a major barrier to adoption. The authors assessed the costs and financial benefits of the CPOE system at Brigham and Women's Hospital over ten years.(More)
PURPOSE To estimate the correlation between the negative appendectomy rate (NAR) and the rate of preoperative computed tomography (CT) in patients suspected of having acute appendicitis who presented to the emergency department during an 18-year period. MATERIALS AND METHODS This retrospective institutional review board-approved, HIPAA-compliant study was(More)
PURPOSE To estimate the prevalence of focal cystic pancreatic lesions (FCPLs) among patients undergoing computed tomographic (CT) or magnetic resonance (MR) imaging at one institution and to examine any variation in radiologists' recommendation practice pattern with regards to FCPLs. MATERIALS AND METHODS Institutional review board approval was obtained(More)
PURPOSE The aim of this study was to assess whether an integrated imaging computerized physician order entry (CPOE) system with embedded decision support for imaging can be accepted clinically. METHODS The study was performed in a health care delivery network with an affiliated academic hospital. After pilot testing and user feedback, a Web-enabled CPOE(More)
OBJECTIVE Our goal was to evaluate trends in the use of radiology with inpatients in the 10-year period of 1984-1993. MATERIALS AND METHODS We retrospectively reviewed administrative data from a 751-bed, tertiary care hospital between October 1, 1983, and September 30, 1993 (Fiscal years 1984-1993). We coded each study by imaging technique: CT, MR(More)
OBJECTIVE Our goal was to develop a software system that allows easy and rapid input of digital radiology images and text reports, at the time of interpretation, into an easily searchable electronic teaching file database using the Internet and the World-Wide Web protocols, servers, and browsers. CONCLUSION Using the Internet, the World-Wide Web, and our(More)
