Three patients with intractable epilepsy, two with brain tumors, and one with encephalitis were imaged with magnetic resonance (MR) and positron emission tomography (PET). MR data were used to construct a three-dimensional (3D) computer model of the brain surface depicting the precentral (movement), postcentral (sensation), left inferior frontal (speech),(More)
BACKGROUND Studies have established that physiologic instability and services mismatching precede adverse events in hospitalized patients. In response to these considerations, the concept of a Rapid Response System (RRS) has emerged. The responding team is commonly known as a medical emergency team (MET), rapid response team (RRT), or critical care outreach(More)
INTRODUCTION Arterial catheterisation is used for continuous haemodynamic monitoring in patients undergoing surgery and in critical care units. Although it is considered a safe procedure, a major complication such as arterial occlusion and limb gangrene can occur. OBJECTIVE To determine the incidence, outcome and potential to avoid complications(More)
Data from single 10-minute magnetic resonance scans were used to create three-dimensional (3-D) views of the surfaces of the brain and skin of 12 patients. In each case, these views were used to make a preoperative assessment of the relationship of lesions to brain surface structures associated with movement, sensation, hearing, and speech.

AIM This paper reports a study of nurses' perceptions about medical emergency teams and their impact on patient care and the nursing work environment. BACKGROUND In many acute care hospitals, nurses can summon emergency help by calling a medical emergency team, which is a team of expert critical care professionals adept at handling patient crisis(More)
OBJECTIVE To study the impact of time of day, day of week and level of patient monitoring on medical emergency team (MET) activation. DESIGN Retrospective observational study of all MET and cardiac arrest events between October 2001 and March 2005. SETTING University of Pittsburgh Medical Center Presbyterian Hospital, a tertiary care teaching facility(More)
OBJECTIVE To study the incidence, outcome and potentially avoidable causes of inpatient cardiopulmonary arrests in a hospital with a "mature" rapid response system (RRS). DESIGN Retrospective observational study of all cardiopulmonary arrest events in 2005. SETTING University of Pittsburgh Medical Center Presbyterian Hospital, a 730-bed academic, urban,(More)
We have developed volumetric-rendering methods for visualizing multimodality, multivariable medical imaging dam This paper describes an integrated 3-D display of data from multiple cross-sectional imaging modalities, including magnetic resonance imaging (MRI) and positron emission tomography (PET), and reports a novel approach for displaying vascular(More)
Image processing and volume rendering have been applied to magnetic resonance (MR) images to produce three-dimensional views of the surface of the brain. Four healthy volunteers and 17 patients with a variety of disorders underwent MR imaging of the head, and these images were processed and subjected to volume rendering. The resulting three-dimensional(More)
The authors describe two cases in which Günther Tulip inferior vena cava filters migrated to the chest, necessitating open-heart surgery for retrieval. In the first case, a 52-year-old man was transferred to their hospital from an outside facility after the filter migrated to the main pulmonary artery during attempted filter placement. In the second case, a(More)
