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 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)
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)
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)
A b s t r a c t While evidence-based medicine has increasingly broad-based support in health care, it remains difficult to get physicians to actually practice it. Across most domains in medicine, practice has lagged behind knowledge by at least several years. The authors believe that the key tools for closing this gap will be information systems that(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)
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)
To determine the utility of spiral computed tomography (CT) in evaluation of carotid artery stenosis, spiral CT images of 20 patients were compared with images obtained with conventional angiography (20 patients), ultrasound (US) (15 patients), and magnetic resonance (MR) angiography (six patients). The category of stenosis was determined for each internal(More)
The Internet provides opportunities for widely distributing educational materials such as teaching files. Since a teaching file is both a tradition and a requirement in an accredited diagnostic radiology training program, many of the same resources can be committed to designing it for Internet access. The advantages include easier availability for the(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)
